1. Overview and System Requirements This section describes the SeeGull® LX receiver, including the applicable system configuration and software requirements.

General Description The SeeGull® LX (Figure 1-1) is a dual-conversion super-heterodyne receiver that includes a Digital Signal Processor (DSP) for signal detection, demodulation, and data acquisition. It uses a control processor for control functions messaging. It was designed for the planning, installation, and maintenance of wireless networks. It is a test tool for signal strength and modulation measurement, engineered for the rigors of the mobile test equipment market.

The DSP processor controls the RF front end, including tuning to the desired channels, and acquires two channels of baseband data. Depending on the protocol and the type of measurement, the SeeGull®

LX receiver can provide the user with critical measurements for managing the quality of the network. See Figure 1-2 for details. The raw data is further processed in the DSP processor to yield the averaged RSSI (Received Signal Strength) data and the base station identifier, statistics of the signal, and other RF measurements. The unit can also be customized to do various levels of protocol analysis. The serial communication link allows the host (IBM PC or a proprietary computer with a USB or an RS-232 interface) to control the operation of the scanner and to receive the measurement results. The RS-232 interface comes standard with 115.2k Baud speed, but can also be factory configured for 38.4k Baud. (Refer to section 3 for more details). If the host is an IBM PC or another Windows computer, the Applications Programming Interface (API), available from PCTEL, makes writing the host software easy. An optional description known as the Interface Control Document (ICD) of the low-level serial protocol development is also available for non-PC applications. For copies of the API and/or the ICD, please contact your PCTEL sales or marketing representative.

Initial Inspection Inspect the shipping container and verify that the contents are complete and match the packing list. The single receiver should look similar to the picture in Figure 1-3. If the contents are incomplete or the SeeGull® LX appears damaged, please call the Technical Support line at 866-384-7877.

Options There are a number of options available for the LX scanners. These are described here. Refer to Section 6 for a complete list of options available for the SeeGull® LX product line with their part number. Please contact your PCTEL sales or marketing representative for pricing and delivery information

HoldOver option for cdma2000/EV-DO The HoldOver for cdma2000 and EV-DO scanners enables users to collect measurements even when a GPS signal is not present. Examples include indoor applications, driving through tunnels or in urban areas where maintaining GPS (which is used by the scanner for both location and CDMA timing) is difficult.

Distance Based Sampling Option

The Distance Based Sampling (DBS) option (part number OP029) is available for the SeeGull® LX scanning receiver. This enables a scanner to support a DBS application, and is available for all models of the LX scanner. The scanner will then be able to receive pulses over an RS-422 interface to control when measurements are taken. For information required to interface a DBS sensor to an LX scanner, refer to the SeeGull® LX Enhanced Interface Control Document (eICD). This describes the required hardware interface and the software techniques to control the scanner for DBS applications.

Distance Based Sampling Kit The Distance Based Sampling (DBS) Kit (part number OP028) is available for the SeeGull® LX scanning receiver. See Figure 1-4 for details. It provides both model tuning and optimization capability in one tool. Information on the DBS applications is provided in Section 4. Traditionally, two separate tools were needed for these functionalities. The DBS option is a cost-effective and user-friendly approach to distance based sampling. For more information, please contact your sales or marketing representative. The Distance Based Sampling option includes a kit containing the following:

Built-In Spectrum Analyzer The built-in spectrum analysis feature provides an effective means to detect and troubleshoot frequency related problems. The scanner measures and reports power spectral density using frequency domain techniques. Frequency span in the RF Band, resolution bandwidth (5, 10, 20, 40, and 80 kHz), and sweep averaging (1, 2, 4, 8, and 16) are adjustable.



System Requirements Typical System Depending on a user’s requirements, various hardware and software components may be used in the scanning system along with the SeeGull® LX scanner. However, in most cases, a typical configuration will include a host IBM or compatible PC connected to the scanner via a serial cable and running the user’s application software. This configuration is illustrated in Figure 1-5.

Antenna Requirements Use a 50 Ohm impedance antenna with an SMA male connector at the end of the cable. Refer to PCTEL’s product offering matrix in section 6 for part number information. Power Source Requirements Use one of the following voltage levels:

• +12 VDC @ 2.4 A (Tri-Band & Dual Receiver)

• +12 VDC @ 1.0 A all others Use a car battery, a 12-volt battery, or an AC/DC adapter. It is imperative that the power source be capable of supplying the receiver with the voltage and current levels as above. It is HIGHLY recommended that the power supply not exceed the working range of the receivers. Applying excessive voltage to the receiver will void the unit’s

warranty. See Figure 1-6 for the location of the power and ground pins on the RS-232 power/connector for the single LX scanner.

3. Operation This section discusses calibration, software upgrades, and integrating the SeeGull® LX receiver into the user’s test system.

Calibration SeeGull® LX receivers are calibrated at the factory. The calibration data is stored in the internal non-volatile memory for each 1 dB step for the whole input signal dynamic range. Recalibration is recommended every year in order to maintain the specified accuracy levels. Please refer to the Calibration Notice in section 5 for more information. Re-calibration is available as an optional service from PCTEL, RF Solutions Group. Note:

Recalibration is Recommended Every Year

Software Upgrades SeeGull® LX scanner stores the application program in internal non-volatile memory, and accordingly, is capable of being upgraded via software. Upgrades may be needed to incorporate new features or bug fixes. Please note that some upgrades can only be performed at PCTEL’s factory.

Operation: Controlling the Scanner and Acquiring Data A unit is controlled, and the measurement data is received via the RS-232 communication link running at 115.2k Baud (factory standard) or 38.4k Baud (please request at time of order). For instructions on how to change the baud rate, please refer to the eICD, or the API. Depending on the PC software used to work with the unit, the following is applicable:

If the user incorporates the scanner into their test system running Windows 2000, use the Application Programming Interface (API) described in References, Item 1 (Preface Section). In case the user has a system that runs an operating system other than Windows, use the description of the serial interface and messages. See References, Item 2 (Preface Section).

cdma2000/EV-DO use of GPS During collection, the cdma2000 and EV-DO scanners utilize a GPS signal to provide accurate timing for measurements of Pilot Delay, Delay Spread, Pilot Number, Aggregate and Peak Ec/Io. If the GPS signal is lost, inaccuracies in these measurements may occur within minutes, unless the HoldOver option is used.

HoldOver Option Operation When a GPS signal is present, the CDMA 2000 and EV-DO scanners use the GPS data for timing information to decode the CDMA Signals. With the HoldOver option, the CDMA2000 and EV-DO scanners will continue accurate decoding of pilots for a period of 2 -4 hours in the absence of any GPS signal. To get the best performance of the HoldOver option during indoor measurements, we recommend that the GPS be locked for at least 45 minutes before using the scanner in an unlocked / holdover mode (with power maintained).



4. DBS Operation If you are developing proprietary software to control the SeeGull® LX receiver, please refer to the LX Applications Programmers Interface (API) or Enhanced Interface Control Document (eICD) for how to control and use the Distance Based Sampling option. Background Typical application requirements: DBS is used primarily for enforcing rules about the distance spacing between measurements. One primary motivator of this type of measuring is the “Lee criteria”. This states that the appropriate distance for measuring a signal is taking 50 measurements within a distance that is 40 times the frequencies wave length. Within the cellular technologies, the common bands are listed here, with the corresponding parameters. The number of required measurements per second for one, two and four channels is given if driving is assumed to occur at 100km/h (app. 62 mph); other sampling rates can be determined for slower speeds. Band 40λ/50

(cm) Meas./sec @100km/h 1 channel

DBS in LX Scanners: The scanners are designed to provide the means to take RSSI measurements based on distance. Using external sensors that provide pulses based on distance (via an RS-485 interface), the scanners can be configured to make measurements for the channels on the scan list once for time a certain number of pulses occur. The InSite application provides the means to “calibrate” the sensor, which determines the correct numbers of pulses per meter. It then allows the user to define

the distance to take another measurement, using guidelines like those listed above. (Of course, other application can be used to interface with the scanners and provide these capabilities.) Scanner measurement speed: Each technology in the LX scanner has a maximum scanning speed (the ability to reliably perform a maximum number of measurements per second) for making RSSI CW (continuous wave) measurements: WCDMA: 600 per second GSM: 150 per second These speeds are achieved regardless of the number of channels selected for measurement. When the scanner is configured to exceed these speeds, error messages are reported and the resulting measurement speed is degraded. This indicates the limits on which selections should be made for scanning. Final scanning speed is based on 4 parameters:

1. Technology of the scanner 2. The band to be measured 3. The distance selected for making

measurements 4. The speed that the scanner is

moving when taking measurements The maximum channels that can be configured using the Lee Criteria above are at 100km/h and 50km/h are given in this table:

Band 40λ/50 (cm) Meas./sec WCDMA GSM

2100 11 252 / 126 2 / 4 0 / 1 1900 12 231 / 115 2 / 5 0 / 1 1800 13 213 / 106 2 / 5 0 / 1 900 26 107 / 53 5 / 11 1 / 2 850 27 103 / 51 5 / 11 1 / 2 450 52 54 / 27 11 / 23 2 / 5

*100km/h / 50km/h LX reporting of measurements: One characteristic of PCTEL’s LX scanners is using stacked mode to achieve these scanning speeds, and works as follows:



• The scans are performed requested, but results are grouped in a large group (up to 255)

• These results are reported from the scanner on 1 second boundaries

• If less than 255 results are produced in a second, one message is reported with the measurements done; if more are produces a set of messages are reported

• The messages with contain a count of results that are a multiple of the number of channels (ex. If 10 channels are requested, there will be up to 250 results in each message)

The result is that the scanners ability to report messages does not limit the measurement speed. When compared to the table above, when the scanner is configured for one channel, in most cases, each 1 second report will contain less that 255 measurements. But, for 2100MHz and 4 channels, each message in a report 150 per second will old 252, so it would provide 4 messages in each report per second with 252 measurements in each message.

SeeGull® LX Manual: Troubleshooting


5. Troubleshooting This section describes a few suggestions for several common problems that might occur. These suggestions are user serviceable.

No Power: Receiver LED’s Not Illuminated Should there be no power displayed on the Power LED located on the face of the receiver, please check the connection first, then the fuse, which is located in the cigarette lighter end of the power cord. Note:

Check The Fuse in the Cigarette Lighter Plug First!

The fuse can be “blown” by a surge in the portable or mobile battery system. A temporarily shorted wire can also cause other problems. If the fuse is not operating normally, it will open up, thereby disconnecting the input power from the SeeGull® LX Receiver. The fuse is the first line of defense should any short, large spike, or other problems occur within the power wiring circuitry. When the fuse “blows”, there will be no power to the receiver. Changing the Fuse in the Power Plug If it is necessary to change the fuse in the power plug, remove the cigarette lighter plug end from the power source. See Figure 5-1 for an illustration of the power plug. Loosen the fuse-holding finger nut by turning it counter-clockwise until the plug comes apart. The fuse is inside the power plug housing and can be removed.

Replace the fuse with an identical 3-amp fuse. ONLY USE a 3-amp! Any other fuse value may cause severe problems with the unit and void the warranty. Insert the new fuse in the housing and re-assemble the plug by turning the knurled finger nut in a clockwise direction. Tighten this nut as tight as you can with your fingers. Note:

Do Not Use Tools to Tighten

Received Signal Strength Appears Low If the received signal strength appears to be lower than expected, it is likely that (1) an incorrect antenna is being used, (2) an antenna is not properly connected or (3) the antenna or antenna cable is damaged. Check the antenna to be used with each receiver to be sure that the correct frequency antenna is being used or that one is even connected. Note:

PCTEL recently released (August 2006) two new antennas that have new bases with a better cable (extended temperature range) and a frequency range wide enough to cover all of our scanners (except the 450 MHz scanners). The first, OP078, replaced the OP042 and OP039; this supports all of the 800, 900, 1800, 1900 and 2100 band scanners.

The second, OP079, will replace OP065; has a built in GPS base and supports all of the 800, 900, 1800, and 1900 band scanners

Until these antennas were released, all PCTEL antennas had a colored cable sleeve to identify the band that is supported. The new antennas will not have a colored cable sleeve to indicate that they work for all bands but the 450 MHz band (those

antennas will continue to have a colored sleeve). Figure 5-4 shows a chart for PCTEL’s color-coding. Verify that all the necessary antennas are included in the shipment and that each is marked. Each antenna comes in a bag that is labeled with a sleeve that identifies the frequency band with which it is to be used (see Figure 5-2 and 5-3). This information must not be lost or mixed up. Antennas cannot be identified by length, shape, or other physical characteristics except the presence or absences of the colored cable sleeve. Note: Some Receivers Require Multiple Antennas. cdma2000 and EV-DO Receivers Require

Two Antennas (RF & GPS) for Proper Operation.

6. Frequently Asked Questions (FAQ) PCTEL’s website provides an up-to-date list of Frequency Asked Questions (FAQ). To see this list go to www.pctel.com, click on the RG Solutions Group link, then Support, then FAQ. At the time of release of this manual the following FAQ questions were available:

SeeGull® LX FAQ

Q What scans can work for WCDMA in DBS mode?

A

WCDMA with DBS only works in the RSSI CW and RSSI Wide mode (there is no supported 30KHz mode like GSM) and no other types of scans (data modes) can be active

Q Is there any recommendation on using CDMA indoors without GPS and without the Network Timing option?

A

The difference between any two consecutive (or not consecutive) pilots is time respective to the system reference. Time is defined in chips. Due to propagation delays, far away from a cell (>10 miles) it is possible that the delay is long enough (chips) for any pilot to be detected as the next one. This is the way CDMA networks are. • When using the holdover option,

the scanner will deviate by one chip every so often due to timing errors. This is in addition to the chips of delay that are due to natural delays and change over time can contribute to the same result. A given pilot is detected as the next one after some time. This does not represent a problem on its own if the customer is aware and simply interprets the results accordingly. Additionally, the customer can go outside at any point during the test and allow the scanner to obtain a new timing reference.

• 87 minutes is the worst case for

pilot to move to the next pilot if the

base station for this pilot is in proximity to the indoor measurement area. If the pilot is coming from further away it can be less than 87 minutes based on the propagation delay from the measured based station to the indoor area that is surveyed. This problem is typically worked around in the field by selecting all the pilots (TopN) or every n and n+1 pilot at the expense of the slower measurement rate.

• The time that will elapse

before one pilot is detected and the next one will depend on room temperature and how much time the scanner is allowed to obtain GPS reference prior to going indoors. In the worst of cases -one goes inside immediately after acquiring GPS- the pilot will be detected as the next one after about 80 minutes. Typically, it will be better especially if the scanner is allowed to acquire GPS for a longer time before going inside a building.

Q What are the differences between CDMA 850 and CDMA2000 850?

A

CDMA 850: * is based on the DX platform * can perform one function at a time (e.g. RSSI CW or Pilot Scan) * can handle one frequency CDMA 2000 850: * is based on the LX platform * can perform multiple functions simultaneously (e.g. RSSI CW and Pilot Scan and Spectrum Analyzer etc.) * can handle multiple frequencies simultaneously * has spectrum analyzer capability (release 2.0 in April '03, other release 2.0 features are Pilot zoom (Temporal Analyzer), DBS (Distance Based Sampling) with RSSI Frequency Scan) * has code domain (option)

Q

For CDMA 850 (869~894MH), do you measure chip offset of specified pilot in good resolution (eq, 1/16 chip or 1/8 chip resolution)?



A

The CDMA 2000 scanner provides a Pilot zoom (Temporal Analyzer) scan which measures the power per chip in a specific pilot. Pilot Scan and Top N Pilot Scan Pilot Delay data mode reports PN offset in chips.

Q For CDMA 850 (869~894MH) do you measure Ec/Io of specified pilot ?

A This is a standard feature of the Pilot scan.

Q For CDMA 850 (869~894MH), do you measure RSSI?

A

CDMA 850 measures RSSI CW (30kHz bandwidth) only. The CDMA 2000 scanner can measure channel power using RSSI scan CW or Wide channel with 30 kHz and 1.25 MHz BW respectively. In addition to this Io-total 1.25MHz channel power is measured and reported in Top N Pilot, Pilot, Code Domain, Pilot Zoom and Pilot Detail scans.

Q For CDMA, is it possible to measure burst pilot [ for case of 0.5sec ON, 1.5sec OFF ]?

A

The current product measures according to the CDMA 2000 (IS-2000) standard. If the pilot is punctured, it is not known how measurement accuracy or ability will be affected.

Q What happens to timing when GPS becomes unlocked for CDMA 2000?

A

The drift at room temperature: typical .033 chip/sec = 2 chips/minute ~ 32 minutes per PN worst case .11 chip/sec = 6.6 chips/minute ~10 minutes per PN NOTE: The aging spec for the oscillator on the LX clock card is 500 ppb/year. This only determines system accuracy if no GPS frequency reference is available.

Q What are the new values for CDMA 2000 Ec/Io thresholds for release 2.0?

A 512 taps = -16dBm, 1024 taps = -19dBm, 2048 taps = -22dBm

Q

For CDMA, is it possible to lock without GPS module using external even second signal?

A There is not a way to feed an external signal for timing into the radio. If

measurement without GPS is necessary, the normal scanner will “hold over” for a period of time until GPS can be established. PCTEL also has a holdover product which can provide accurate results for hours of operation once GPS is lost (assuming GPS lock is first acquired). Release 3.0 of the CDMA 2000 scanner will provide a GPS priority mode which will use GPS for timing when possible and if not it will use the strongest pilot’s sync channel to determine timing.

Q What would be the effects of Aggregate when using the scanner indoors?

A

Using the Scanner Aggregate Ec/Io measurement indoors has same effect as using this measurement outdoors. Aggregate Ec/Io value reflects a specific multi path environment experienced indoors or outdoors.

Q How is the Aggregate Ec/Io parameter reported by the pilot scan calculated?

A Aggregate Ec/Io is calculated in +/- 25 chips window from the Peak Ec/Io by aggregating all the Ec/Io components that cross user supplied PN Threshold.

Q What is the difference between the "RSSI scan" and "Spectrum Analyzer" mode in the SeeGull® LX WCDMA Scanner?

A

The differences lie in the corresponding objectives and ways of implementation of the two modes. "RSSI scan" modus, on one hand, is used for obtaining average power in one of the two signal bandwidths of the scanner. Accordingly, measures are taken to ensure high accuracy and stability of the results. The Spectrum Analysis is intended to provide a tool that shows a wealth of information about the signal spectrum that is not obtainable from the channel power measurement. Using Spectrum Analysis, one can analyze a fast-changing spectrum of an unstable transmitter, as an example. The RSSI measurement in this case will most often show a normal smooth picture, but the spectrum display, if used with an appropriate resolution bandwidth, will show an erratic behavior due to the fast update rate and lack of averaging. In terms of implementation, the RSSI



measurement uses analog and digital filters to select the right frequency band and subsequently measure total power. The SA measurement uses a segmented FFT approach that ensures various resolution bandwidths and fast update rates.

Q Is the built-in GPS receiver needed for WCDMA?

A

No. As is indicated in the product documentation, the scanner will work in areas without GPS coverage, continuously. However, with the coverage, the scanner provides an absolute time-offset measurement as well as navigation data for mapping. In order to avoid any possible confusion, let us emphasize that the GPS receiver is always included in the scanner, whether or not it is being used by the customer. The only exception are the GSM models that can be purchased without navigation, which have no GPS device included.

Q Are the sec. sync for WCDMA also detected and measured in top N mode?

A Yes

Q Are the WCDMA PSCH measurements averaged over certain timeslots? How many ? Can that be defined by the user?

A The PSCH measurement is always performed over 16 time slots. This is not configurable by the user.

Q Are the secondary sync channels also detected and measured in top N mode for WCDMA?

A Yes.

Q For the PSCH detection you are distinguishing between "detectable" and "discernable". What is the difference?

A

The difference is as follows. The "detectable" signal is a signal that is positively found virtually every scan. The definition also implies the intrinsic step of (nonlinear) detection (decision, as in Top-N). In practice, the criterion we use is 95% probability of detection. The notion of a "discernable" signal, on the other hand, is more "analogue" in nature. It hails from the era of CRT-based radars, where the phosphorescence of the screen served as the video integrator. The decision was made by the eye of the operator. So, averaging is inherent in this definition, as well as a relatively subjective nature of the decision. In our case, we call a signal "discernable" in the case when we can "see" the presence of the signal over noise after averaging a few scans. No threshold is being applied to the measurement before averaging, which makes this parameter suitable in the case of "Pilot Scan" (as opposed to Top-N). In practice, the number of traces is 10, and the necessary SNR after averaging is set to 0.5 dB (that

Q Why does the noise pedestal increase around strong carriers for WCDMA?

A

For WCDMA signals above around -35 dBm our radio will introduce attenuation to protect itself from overflow (overload). This attenuation causes increase in the radio noise floor. Without this we would not be able to measure WCDMA signals up to -20 dBm. Same will happen with the CW signals (that have lower crest factor than WCDMA signals). This noise floor behavior is typical for all spectrum analysis tools

Q Why is peak psch and ssch skewed toward lower values?

A

PSCH is more susceptible to fading than CPICH. This opens a whole issue of how to post-process data, averaging in presence of fading, Lee criterion, etc. The nature of the beast is such that it skews the variation towards favoring lower values whenever degrading factors are present. As a minimum, do not attempt to average results expressed in decibels but in a linear domain instead.

Q How can the measured WCDMA wide band RSSI be lower than -110dBm since the thermal noise floor is at -108dBm?



A PCTEL can account for the thermal noise and eliminate it to some extent in the RSSI measurement. This enables us to measure RSSI at lower levels

Q What is the description of DBS Windowing Issue (Useful for GPS Windowing)?

A

The SeeGull LX radio running controller versions 1.13.2.2 and preceding exhibit a pooling behavior with respect to Distance Based Sampling operation. The diagram below will be used to illustrate the problem (see picture enclosed). The first thing of interest is the Message Output waveform at the top of the diagram. When the SeeGull Lx is operating in 'triggered mode' (a.k.a. DBS Mode), the scanning receiver takes a measurement based on a user-defined distance. The measurements are buffered in the radio, and output on 1.0-second intervals from the product (TE above). During a TE period, the number of measurements that occurred is based upon the desired sampling distance and the distance traveled during that time. For the purpose of this discussion, we will assume that the GPS information is aligned EXACTLY with the output messages. We will assume that the vehicle using the system is traveling at a constant velocity (zero acceleration) for the sake of this explanation. In reality, it is nearly impossible for a standard automobile to maintain exactly the same velocity at all times. The conclusions drawn herein are the same for non-zero accelerations, but we'd have to use integration, which would needlessly complicate understanding of the issue. Using these assumptions, there is one speed for every desired distance interval (referred to here as the 'perfect velocity' or Vp) at which there will be exactly the same number of measurements taken and outputted in each message from the radio. Since the distance between measurements is also constant at a user-selected interval (DS), due to the DBS sensor, we can define the 'perfect time' (Tp) at which there

will be exactly the same number of measurements taken and outputted in each message from the radio. The relationship between Vp and Tp would be Tp = Ds/Vp. This same relationship exists for all velocities and corresponding measurement periods. Now that we have detailed the 'perfect' cases, we can investigate the behavior that results when the information is directly plotted in a mapping package. The second waveform in the picture above shows the case where the velocity (V1) is greater than Vp. In this situation, the time between measurements will be less than the perfect time. This results in there occasionally being an Extra measurement in the output message, from time to time. In the diagram above, if we were traveling at Vp we'd expect one measurement per output message. DBS 1 shows the case when on the third output message, we got two measurements returned in the output message. The number of output messages between the output messages with the extra measurement (NEM ) is given by: NEM = (V / Vp - 1)-1 The third waveform in the picture above shows the case where the velocity (V2) is less than Vp. In this situation, the time between measurements will be greater then the perfect time. This results in there occasionally being a missing measurement in the output message, from time to time. In the diagram above, if we were traveling at Vp we'd expect one measurement per output message. DBS 2 shows the case when on the third output message, we got zero measurements returned in the output message. The number of output messages between the output messages with the missing measurement (NEM ) is given by: NMM = (Vp / V - 1)-1 Note that in both the cases above, if the speed being traveled is an integer multiple or divisor of the perfect velocity, then there will be no extra or missing measurements.



The issue with the extra/missing samples is most obvious when data points are plotted on a map in a product like MapInfo® without using any interpolation. Since we can new GPS Data on every output message (due to our assumption above), we would label each point with the location in memory at the time the message is received in the host from the scanning receiver. The would result in the case of the missing output scenario (DBS 2) in a map that looks like its missing a point every once in a while. The way to address this when using distance-based sampling is to apply an algorithm to the returned measurements that using interpolation to place the measurement point at the appropriate point between the two GPS readings. The actual algorithm used is a matter of some discussion, and there are many choices depending upon the goal of the data collection. One simple example would be to assume a straight line between two GPS points, and space the number of measurements that occurred during that second equally along that line. For most cases, this is sufficient. If more accuracy of data location is necessary, than sources on interpolation can be consulted for more robust algorithms. Remember that due to the sensor, you can rely on the distance traveled between two measurements to be very nearly the specified distance. As a note, this same scenario can exist absent of DBS, due to GPS information being available only once a second. If there were multiple output messages between the GPS messages, then the simple algorithm would lump the measurements to the GPS location of the nearest preceding second. As with the DBS case above, interpolation can be used to spread the measurements out more realistically over the interval. Another common technique is 'binning', which takes ALL of the measurement and averages them to single point based upon overlaying a grid with the desired resolution.

As can be seen above, this is a fairly complex issue, and will change from configuration to configuration. This issue has not been addressed to date, and exists in all versions of the product produced so far.

Q Does WCDMA scanner report 'delay' measurement?

A

If you mean, can the customer measure the delay of the signal, the answer is Yes. Absolute time offset of a selected WCDMA pilot in chips is measured. Ranges of the time offset are from 0 to 38399. It is also possible to estimate the clock frequency offset of a Pilot by continuously observing Time Offset parameter change for a given Pilot.

Q What is the difference in measurement speed between With PSCH and Without PSCH?

A With PSCH present: 525ms for one pilot. Without PSCH present: 60ms (minimum) for one pilot.

Q Any usage of WCDMA scanner to correct a pilot pollution?

A

Pilot pollution means there are more active pilot than a handset can measure (#pilot present > #rake receivers in the phone), so by looking at the pilot measurement of the carrier or the Top N measurement, if there are more pilots present than a UMTS handset can handle, then it indicates pilot pollution present. Thus the WCDMA scanner can help to identify the presence of pilot pollution.

Q

My question about the LX scanner is: does it present average RSSI values of the samples that it measures? If yes, how is this averaging done and over how many samples?

A

The RSSI value an LX scanner returns is a combination of direct sample average and other non-linear methods. It is more flavored towards instantaneous “stable” power than the average power.

Q I would like to know more details how the scanner is calculating the C/I values.

A In the case of GSM, the Scanner is calculating C/I based on the FCCH burst. It



measures correlated power of the FCCH burst C and total power Io for the same time window. C/I is than calculated as: C/I = C/(Io-C)

Q GPS takes longer to lock than normal.

A If you have had your LX scanner for about 2 years, then it may need to be returned to PCTEL for recalibration. The user will need to pay a calibration fee.

Q How do you decode the GPS data to the proper format (degree, minute, second)?

A

Our scanner reports GPS Lat/Long in Radians... Please see legend below then the conversion to degrees / minutes / seconds: Legend: -------------- D = Degrees M = Minutes S = Seconds .m = Decimal Minutes .s = Decimal Seconds DM.m = Degrees, Minutes, Decimal Minutes (eg. 45 ο 22.6333) D.d = Degrees, Decimal Degrees (eg. 45.3772ο) DMS = Degrees, Minutes, Seconds (eg. 45 ο 22'38") ------------------------------------------------ Radians (taken from scanner) * 57.2957795 = Degrees, Decimal Degrees (D.d) then D.d --> DM.m (45.3772 --> 45 ο 22.6333) - Multiply .d by 60 to get M.m (.3772*60=22.6333) DM.m --> DMS (45 ο 22.6333 --> 45� 22'38")

- Multiply .m by 60 to get S(.6333*60=38)

Q

We are doing scan for spectral clearance ( RF Ch RSSI Scan.), and on usage some of the times the spectrum window show error message "RF attenuation is automatically tuned on", As well the RSSI measured for a particular channel in spectrum window

is not the same RSSI value measured for the same channel in RSSI window at a given time. Could you please clarify? The question here is why RF attenuation is automatically tuned on ?

A

RF attenuator is automatically turned on to prevent overflow in the unit, avoid non-linear effects and extend the dynamic range of unit at the expense of the noise figure degradation. This happens each time instantaneous (peak) power of the signals in the 5 MHz IF bandwidth crosses around -35 dBm. This is a normal behavior same as in any Spectrum Analyzer instrument, and should not be treated as a system error. There could be some measurement difference with or without RF attenuator been turned on, but the measurement error should be with in PCTEL specification of RSSI accuracy.

Calibration Notice PCTEL recommends a yearly re-calibration of its scanning receivers. This recommendation is based on our understanding of various factors that may affect accuracy of the measurement results. The following factors have been identified as potential sources of accuracy degradation: crystal oscillators’ aging; amplifier stages’ gain drift; LC and ceramic filters’ part value change (due to aging, as an example). Although our experience has been that in most cases the units coming back for re-calibration are still well in the specified accuracy margin, in some cases re-calibration is necessary. The SeeGull® scanning receivers are calibrated for several sources of variations including amplitude levels, ambient temperature, input frequency, and internal noise levels for narrow and wide channel bandwidths. The calibration parameters are stored as single values or arrays in the scanners’ non-volatile memory. Automated test and calibration stations use proprietary software which performs the process with no or minimum human intervention. The calibration process is followed by a fully automated production test. The test results are stored in a central quality database and they are extracted and used for periodic quality audits. Every unit that passes the calibration and test process successfully receives a Certificate of Calibration. This Certificate is shipped back with the unit.

SeeGull® LX Manual: Support


The complexity of the calibration process precludes field calibration. It is highly recommended that PCTEL’s scanning receivers be returned to the factory annually to maintain the units’ exceptional measurement capability.
