Amplitude accuracy: Greater of ±2% or ±0.5V.
Provided termination: 50.0 ± 1%
Voltage rise & fall times: ≤ 10 ns (20%-80%) ≤ 0.5 ns (20%-80%)
Pulse width ( WHM): 250 ns to 250 us 50 to 200 ns
Droop (at max. pulse width): ≤ 2%
Overshoot (at max. amp.): ≤ 5%
PR : Internal trigger: 1 Hz to 10 kHz, External trigger: 0 Hz to 10 kHz
Duty cycle (max): 0.25% 0.2%
Polarity5: Positive or negative (specify)
Propagation delay: ≤ 150 ns (Ext trig in to pulse out)
Jitter: ± 100 ps ± 0.03% of sync delay (Ext trig in to pulse out)
Output connector: BNC SMA
Probe attachment style: lexible clamping cable on output module6. The output module is
connected to the front panel by a 12" / 30 cm coaxial cable.
Trigger modes: Internal trigger, external trigger (TTL-level pulse, > 10 ns, 1 kΩ input impedance),
front-panel “Single Pulse” pushbutton, or single pulse trigger via computer command.
Variable delay:
(Sync to main out) 0 to 1.0 seconds, for all trigger modes (including external trigger). Common to all outputs.
Sync output (will drive 50Ω): +3 Volts, 100 ns
Gated operation: Synchronous, active high or low, switchable.
GPIB and RS-232 control2: Standard feature on all -B units.
Ethernet port, for remote
control using VXI-11.3, ssh,
telnet, & web:
Optional7. Recommended as a modern alternative to GPIB / RS-232.
See http://www.avtechpulse.com/options/vxi for details.
LabView drivers: Check for available downloads at http://www.avtechpulse.com/labview.
Power requirements: 100 - 240 Volts, 50 - 60 Hz
Dimensions: 100 mm x 430 mm x 375 mm (3.9” x 17” x 14.8”)
Mounting: Any. Add -R5 to the model number to add a rack-mount kit.
Temperature range: +5°C to +40°C
1) -C suffix indicates stand-alone lab instrument with internal clock and line powering. (See http://www.avtechpulse.com/formats for the basic instrument formats). Not
recommended for new designs. Use -B versions instead.
2) -B suffix indicates IEEE-488.2 GPIB and RS-232 control of amplitude, pulse width, PR and delay (See http://www.avtechpulse.com/gpib).
3) or operation at amplitudes of less than 10% of full-scale, best results will be obtained by setting the amplitude near full-scale and using external attenuators on the
output.
4) The amplitude of the AVR-3-PW-TEK2-C may also be controlled by a 0 to +10V DC voltage applied to a rear-panel BNC connector, in addition to the standard front-panel
controls.
5) Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative).
6) An optional additional output module is available for "Output 2" of the AVR-3-PW-TEK3-B, which is suitable for use with CT-1 and CT-2 current probes. This output module
uses a very short length of de-solderable bus-bar wire (instead of flexible cable) which must be fed through the probe. Add the suffix "-CT" to the model number to specify
this option.
7) Add the suffix -VXI to the model number to specify the Ethernet port.
