INTRODUCTION & SPECIFICATIONS

Model AVR-3-PW-C-P-TEK2 is a special order item which was custom designed for Tektronix, for the testing of current probes (such as the A6303 probe). Specifications are as follows:

Model designation: AVR-3-PW-C-P-TEK2

Description: The AVR-3-PW-C-TEK2 generates a 10 ns rise time voltage pulse (up to +250 Volts, 0.25 to 250 µs), which is accessible at the front panel OUT terminal. A shorting bar is connected between the OUT and IN terminals and the current probe is placed over the shorting bar. The IN terminal connects to ground via a 50 Ohm termination. A variable current of up to 5.0 Amperes is defined by the 250 Volt pulse and the 50-Ohmtermination.

For other applications, the OUT terminal may be used to pulse a user-supplied 50 Ohm load, if desired. In this case, the shorting bar and the “IN” terminal are not used.

Output Amplitude: up to +250 Volts to RL ≥ 50 Ohms(ie 5 amperes peak current). Ten-turn locking dial control.

Output pulse width: 250 ns to 250 us.3-position range switch and ten-turn fine control.

Output connectors: Two SMA connectors. Output Shorting bar connects between two connectors. Tektronix probe clips over this shorting bar.

Rise, fall time (20%-80%): ≤ 10 ns

Max duty cycle: 0.25 % (eg PRF max 25 Hz for PW=250 us).

Overshoot at max output: ≤ 5%

Droop (at max pulse width): ≤ 2%

Chassis: 3.9” x 17” x 14.8”

Other: See standard AVR-3-C, pages 43 and 44 Cat. No. 11

REGULATORY NOTES

FCC PART 18

This device complies with part 18 of the FCC rules for non-consumer industrial, scientific and medical (ISM) equipment.

This instrument is enclosed in a rugged metal chassis and uses a filtered power entry module (where applicable). The main output signal is provided on a shielded connector that is intended to be used with shielded coaxial cabling and a shielded load. Under these conditions, the interference potential of this instrument is low.

If interference is observed, check that appropriate well-shielded cabling is used on the output connectors. Contact Avtech ([email protected]) for advice if you are unsureof the most appropriate cabling. Also, check that your load is adequately shielded. It may be necessary to enclose the load in a metal enclosure.

If any of the connectors on the instrument are unused, they should be covered with shielded metal “dust caps” to reduce the interference potential.

This instrument does not normally require regular maintenance to minimize interferencepotential. However, if loose hardware or connectors are noted, they should be tightened. Contact Avtech ([email protected]) if you require assistance.

FRONT PANEL CONTROLS

1. POWER Switch. This is the main power switch. When turning the instrument on, there may be a delay of several seconds before the instrument appears to respond.

2. REPETITION RATE Controls. When triggering internally, the range switch sets the pulse repetition frequency of the internal oscillator to one of four range:

RANGE 1 1 Hz - 10 HzRANGE 2 10 Hz - 100 HzRANGE 3 100 Hz - 1 kHzRANGE 4 1 kHz - 10 kHz

The “FINE” knob varies the frequency within each range.

3. DELAY Control. Controls the relative delay between the reference output pulse provided at the TRIG output (4) and the main output (5). This delay is variable over the range of 0.25 to 250 us. The TRIG output precedes the main output when the ADVANCE-DELAY switch is in the ADVANCE position and lags when the switch is in the DELAY position.

4. TRIG Connector. When the MODE switch (item 9) is set to the “EXT” position, a TTL-level pulse applied to this connector will trigger the instrument. The instrument triggers on the rising edge of this input. The input impedance of this input is 1 kΩ. (Depending on the length of cable attached to this input, and the source driving it, it may be desirable to add a coaxial 50 Ohm terminator to this input to provide a proper transmission line termination. The Pasternack (www.pasternack.com) PE6008-50 BNC feed-thru 50 Ohm terminator is suggested for this purpose.)

When the MODE switch (item 8) is set to the “INT” position, this connector is

14

11

1 10 7 5

4 3

6892

used as an output that generates a 200 ns wide TTL-level pulse for each trigger event. This output can be used to trigger an oscilloscope, or other test equipment. The separation between the main output pulse and the TRIG output pulse is controlled by the DELAY controls and the ADVANCE/DELAY switch. For this output to operate correctly, the delay setting must be less than the period.

5. OUT Connector. SMA connector provides 0 to +250 Volt output to a 50-Ohm load. (5) and (6) are normally connected together via the shorting bar, as discussed in later sections of this manual.

Caution: Voltages as high as +250V may be present on the center conductorof this connector. Avoid touching this conductor. The center conductor is not user-accessible when the supplied shorting bar is installed.

6. IN Connector. This SMA input connects to the internal 50-Ohm load. (5) and (6) are normally connected together via the shorting bar, as discussed in later sections of this manual.

Caution: Voltages as high as +250V may be present on the center conductorof this connector. Avoid touching this conductor. The center conductor is not user-accessible when the supplied shorting bar is installed.

7. PW Control. A one-turn knob and three-position range switch vary the output pulse width from 0.25 us to 250 us. The minimum and maximum pulse width (PW) for each range and the corresponding maximum pulse repetition frequency(PRF) are as follows. Note that the unit may fail if operated at duty cycles exceeding 0.25%.

PW min PW max

Range 1 0.25 us 2.5 us(PRF max) (10 kHz)(2.5 kHz)

Range 2 2.5 us 25 us(PRF max) (2.5 kHz) (250 Hz)

Range 3 25 us 250 us(PRF max) (250 Hz)(25 Hz)

8. AMP Control. This ten-turn locking dial varies the output pulse amplitude from 0 to +250 Volts (to 50 Ohms).

9. INT/MAN/EXT A/EXT B Mode Switch. With this switch in the INT position, the repetition rate of the unit is controlled by an internal oscillator, which in turn is controlled by the REPETITION RATE controls.

With the switch in the EXT A position, the unit requires a 50 ns (or wider) TTL

15

level pulse applied at the TRIG input in order to trigger the output stages. The output pulse width is set by the front-panel controls in this mode.

With the switch in the EXT B position, the unit requires a 0.25-250 us wide TTL level pulse applied at the TRIG input in order to trigger the output stages. The output pulse width is equal to the input pulse width in this mode.

For a single pulse output, the switch should be in the “MAN” position and then push the SINGLE PULSE pushbutton (10).

10.SINGLE PULSE Pushbutton. When the INT/MAN/EXT A/EXT B switch is in the “MAN” position, the instrument can be triggered by pressing this pushbutton. A single pulse is generated for each button press.

11. OVERLOAD Indicator. When the instrument is powered, this indicator is normally green, indicating normal operation. If this indicator is yellow, an internalautomatic overload protection circuit has been tripped. If the unit is overloaded (by operating at an exceedingly high duty cycle or by operating into a very low impedance), the protective circuit will disable the output of the instrument and turn the indicator light yellow. The light will stay yellow (i.e. output disabled) for about 5 seconds after which the instrument will attempt to re-enable the output (i.e. light green) for about 1 second. If the overload condition persists, the outputwill be disabled again (i.e. light yellow) for another 5 seconds. If the overload condition has been removed, the instrument will resume normal operation.

This overload indicator may flash yellow briefly at start-up. This is not a cause for concern.

Overload conditions may be removed by:

Reducing repetition rate Reducing pulse width Increasing the load impedance Reducing the output amplitude

16

REAR PANEL CONTROLS

1. AC POWER INPUT. An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. One end of the detachable power cord that is supplied with the instrument plugs into this socket.

2. AC FUSE DRAWER. The two fuses that protect the AC input are located in this drawer. Please see the “FUSES” section of this manual for more information.

3. DC FUSES. These two fuses protect the internal DC power supplies. Please see the“FUSES” sections of this manual for more information.

4. EA SWITCH AND INPUT. When this switch is set to the “INT” position, the output amplitude is controlled by the front-panel amplitude dial. When this switch is set to the “EXT” position, the output amplitude is controlled by the voltage applied to the “A” BNC connector. 0V in corresponds to zero amplitude, and +10V DC in corresponds to maximum amplitude (+250V). The input impedance of the “A” connector is > 10 kΩ.

GENERAL INFORMATION

TEST ARRANGEMENT

The AVR-3-PW-C-TEK2 generates a 10 ns rise time voltage pulse (0 to +250 Volts, 0.25 to 250 µs), which is accessible at the front panel OUT terminal. A shorting bar is connected between the OUT and IN terminals and the current probe is placed over the shorting bar. The IN terminal connects to ground via a 50 Ohm termination. A variable current of up to 5.0 Amperes is defined by the 250 Volt pulse and the 50-Ohm termination. The basic test arrangement is illustrated below:

For other applications, the OUT terminal may be used to pulse a user-supplied 50 Ohmload, if desired. In this case, the shorting bar and the “IN” terminal are not used.

SHORTING BAR

The shorting bar allows a Tektronix current probe to be clamped around it. The current bar is reversible; it may be installed in either orientation. A photo of the shorting bar is shown below:

MECHANICAL INFORMATION

TOP COVER REMOVAL

If necessary, the interior of the instrument may be accessed by removing the four Phillips screws on the top panel. With the four screws removed, the top cover may be slid back (and off).

Always disconnect the power cord and allow the instrument to sit unpowered for 10 minutes before opening the instrument. This will allow any internal stored charge to discharge.

There are no user-adjustable internal circuits. For repairs other than fuse replacement, please contact Avtech ([email protected]) to arrange for the instrument to be returned to the factory for repair. Service is to be performed solely by qualified service personnel.

Caution: High voltages are present inside the instrument during normal operation. Do not operate the instrument with the cover removed.

ELECTROMAGNETIC INTERFERENCE

To prevent electromagnetic interference with other equipment, all used outputs should be connected to shielded loads using shielded coaxial cables. Unused outputs should be terminated with shielded coaxial terminators or with shielded coaxial dust caps, to prevent unintentional electromagnetic radiation. All cords and cables should be less than 3m in length.

20

MAINTENANCE

REGULAR MAINTENANCE

This instrument does not require any regular maintenance.

On occasion, one or more of the four rear-panel fuses may require replacement. All fuses can be accessed from the rear panel. See the “FUSES” section for details.

CLEANING

If desired, the interior of the instrument may be cleaned using compressed air to dislodge any accumulated dust. (See the “TOP COVER REMOVAL” section for instructions on accessing the interior.) No other cleaning is recommended.
