5. EQUIPMENT UNDER TEST

5.1. DESCRIPTION OF EUT The AR5BXB72 is designed for 802.11a/b/g/n applications using the AR541X/51XX chipset with a PCIExpress Minicard interface. It has three receive chains and two transmit chains (2x3 configuration). The 2x3 configuration is implemented with two outside chains (Chain 0 and 2) as Tx/Rx and the middle chain (chain 1) as Rx only. A 2x2 configuration is implemented by depopulating the middle receive chain; in this configuration the transmit chains are identical to the 2x3 configuration. The 2x2 version, when marketed, will have a unique model ID to differentiate it from the fully configured version.

5.2. DESCRIPTION OF AVAILABLE ANTENNAS The 2x3 configuration utilizes a set of three identical PIFA antennas (maximum gain is 6.5dBi in the 5.2 GHz band and 7.5dBi in the 5.5 GHz band).

5.3. MAXIMUM OUTPUT POWER WITH SPECIFIED ANTENNAS The highest average combined conducted output power under normal environmental conditions in each frequency range is as follows:

5.4. MINIMUM OUTPUT POWER The lowest average combined output power level under normal environmental conditions is 8 dBm for all modes.

Frequency Range Output Power Output Power(MHz) (dBm) (mW)

5150 - 5350 14.33 27.105470 - 5725 15.19 33.04


Page 8 of 86


5.5. OUTPUT POWER WITH REDUCED GAIN ANTENNAS The maximum conducted power level for antenna assemblies with lower gains than specified above is determined by the EIRP limit minus the antenna assembly gain minus correction factors that account for environmental and other limiting factors, subject to a maximum conducted level above which the EUT is unable to comply with the In-band mask and Out-of-band spurious requirements. Preliminary test results demonstrate that there is a maximum power level above which the EUT will not meet In-band mask. Final tests were performed with the Mid Channel set to the maximum power at which the EUT continues to comply with the In-band mask. Preliminary test results demonstrate that the cabinet radiation shows only insignificant changes as a function of power level, over the range of power levels documented in this report. Final conducted spurious emissions were measured with the Mid Channel set to the maximum power level at which the EUT complies with the In-band mask. Results show that the EUT complies with the Out-of-band spurious limit at this power level. The equation describing the relationship between output power and antenna assembly gain in the Lower Band is: Lower Band Maximum Combined Conducted Power at normal environmental conditions = (23 dBm EIRP limit) - Antenna Gain - (2.5 dB due to Power Density limiting factor) No additional correction factor is required for extreme environmental effects since the margin to the EIRP limit is greater than the margin to the Power Density limit. The equation describing the relationship between output power and antenna assembly gain in the Lower Band is: Upper Band Maximum Combined Conducted Power at normal environmental conditions = (23 dBm EIRP limit) - Antenna Gain - (0.4 dB due to extreme environmental effects) No additional correction factor is required for Power Density since the margin to the Power Density limit is greater than the margin to the EIRP limit.

LOWER BAND OUTPUT POWER WITH REDUCED GAIN ANTENNAS Lower Band Combined Average Conducted Power = 20.5 dBm - Antenna Assembly Gain, with a maximum power level of 22.85 dBm.

UPPER BAND OUTPUT POWER WITH REDUCED GAIN ANTENNAS Upper Band Combined Average Conducted Power = 22.6 dBm - Antenna Assembly Gain, with a maximum power level of 22.97 dBm.

MEASUREMENT SYSTEM FREQUENCY REFERENCE Lock the signal generator and the spectrum analyer to the same reference source as follows: Connect the 10 MHz OUT (SWITCHED) on the spectrum analyer to the 10 MHz IN on the signal generator and set the spectrum analyzer 10 MHz Out to On.

SYSTEM CALIBRATION Adjust the Master Step Attenuator to 40 dB, the Link Step Attenuator to 70 dB, and the Slave Step Attenuator to 70 dB. If required, disconnect the spectrum analyzer, Master Device, and Slave Device from the test system. Terminate the Common port of the Spectrum Analyzer Combiner/Divider, Port 2 of the Master Diversity Combiner/Divider, and Ports 1 and 2 of the Slave Diversity Combiner/Divider. Leave, or connect, the appropriate cable to Port 1 of the Master Diversity Combiner/Divider and connect the free end (Master Device end) of this cable to the spectrum analyzer. Adjust the signal generator and spectrum analyzer to the center frequency of the channel to be measured. Set the signal generator to CW mode. Set the RBW of the spectrum analyzer to 10 kHz and the span to 100 kHz. Adjust the amplitude of the signal generator to yield a measured level of –64 dBm on the spectrum analyzer. Without changing any of the instrument settings, reconnect the spectrum analyer to the Common port of the Spectrum Analyzer Combiner/Divider, then remove the cable from Port 1 of the Master Diversity Combiner/Divider and replace this cable with a termination. Measure the amplitude and calculate the difference from –64 dBm. Adjust the Reference Level Offset of the spectrum analyzer to this difference. Confirm that the signal is displayed at –64 dBm. Readjust the RBW and VBW to 3 MHz, set the span to 10 MHz, and confirm that the signal is still displayed at –64 dBm. This Reference Level Offset setting is used for all tests for which the Master Step Attenuator is set to 20 dB. The spectrum analyzer displays the level of the signal generator as received at the antenna ports of the Master Device. The interference detection threshold may be varied from the calibrated value of –64 dBm and the spectrum analyzer will still indicate the level as received by the Master Device. The Link Step Attenuator and Slave Step Attenuator settings may be changed without affecting the System Calibration. The System Calibration process must be repeated for different settings of the Master Step Attenuator to determine the Reference Level Offset associated with each Master Step Attenuator setting.

INTERFERENCE DETECTION THRESHOLD ADJUSTMENT Set the signal generator to produce the specified radar waveform, trigger a burst manually and measure the amplitude on the spectrum analyzer. Readjust the amplitude of the signal generator as required so that the peak level of the waveform is at a displayed level equal to the required or desired interference detection threshold.

ADJUSTMENT OF DISPLAYED TRAFFIC LEVEL Establish a link between the Master and Slave, adjusting the Link Step Attenuator as needed to provide an adequate RSS level at the Master and Slave devices. Stream the video test file to generate WLAN traffic. Adjust the Slave Step Attenuator so that the WLAN traffic level from the Slave, as displayed on the spectrum analyzer, is at lower amplitude than the radar detection threshold. Confirm that the displayed traffic is from the Slave Device by changing the setting of the Slave Step Attenuator and verifying that the displayed traffic level changes accordingly. Confirm that the displayed traffic does not include Master Device traffic by changing the setting of the Master Step Attenuator and the Link Step Attenuator and verifying that the displayed traffic level does not change. Reset all Step Attenuators to their previous settings. If the above conditions cannot be met, use a different setting of the Master Step Attenuator, performing a new System Calibration and Interference Detection Threshold Adjsutment as required for the new Master Step Attenuator setting.

8.7.3. DESCRIPTION AND SETUP OF EUT AND SUPPORT EQUIPMENT

OVERVIEW WITH RESPECT TO DFS REQUIREMENTS The EUT is a Slave Device. The highest power level within the 5250-5350 MHz and 5470-5725 MHz bands is less than 23 dBm EIRP therefore a radar detection function is not required. The rated output power of the ancillary Master unit is > 23dBm (EIRP). Therefore the required interference threshold level is –64 dBm. After correction for antenna gain and procedural adjustments, the required conducted threshold at the antenna port is –64 + 4 + 10 = –50 dBm. The calibrated conducted DFS Detection Threshold level is set to –64 dBm. The tested level is lower than the required level hence it provides margin to the limit. WLAN traffic is generated by streaming the video file TestFile.mp2 “6 ½ Magic Hours” from the Master to the Slave in full motion video mode using the media player with the V2.61 Codec package. This provides approximately 50% channel loading.

8.7.5. CHANNEL MOVE TIME AND CHANNEL CLOSING TRANSMISSION TIME RESULTS

REPORTING NOTES The reference marker is set at the end of last radar pulse. The delta marker is set at the end of the last WLAN transmission following the radar pulse. This delta is the channel move time. The aggregate channel closing transmission time is calculated as follows: Aggregate Transmission Time = (Number of analyzer bins showing transmission) * (dwell time per bin)
