SPECIFICATIONS
Model
1
:
AVR-3HE-B
Amplitude (into
≥ 50Ω)
2,3,5
:
<10 to 200V
Maximum output current:
4A
Rise & fall times (20%-80%):
≤ 10 ns
Pulse width (FWHM):
50 ns to 100 us
Maximum PRF:
100 kHz
Maximum duty cycle and
average output power:
Standard: 10%, 80W
With -XP2 option: 20%, 160W
Polarity
4
:
Positive or negative or both (specify).
Dual polarity not available with -XP2 option.
Output Impedance:
1.5 Ω, approximately
Propagation delay:
≤ 150 ns (Ext trig in to pulse out)
Jitter:
± 100 ps ± 0.03% of sync delay (Ext trig in to pulse out)
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.
In the external trigger mode, the pulse width may be set by the instrument,
or it may be set to track the input pulse width.
Variable delay:
Sync to main out: 0 to 1.0 seconds, for all trigger modes (including external trigger).
Sync output:
> +3 Volts, > 50 ns, will drive 50 Ohm loads
Gated operation:
Synchronous or asynchronous, active high or low, switchable.
Connectors:
Out, Trig, Sync, Gate: BNC
GPIB & RS-232 control

Ethernet port, for remote
control using VXI-11.3, ssh,
telnet, & web:
Included. Recommended as a modern alternative to GPIB / RS-232.

for details.
Settings resolution:
The resolution of the timing parameters (pulse width, delay, period) varies,
but is always better than 0.15% of (|set value| + 20 ns).
The amplitude resolution is < 0.1% of the maximum amplitude.
Settings accuracy:
Typically ± 3% (plus ±1V or ± 2 ns) after 10 minute warmup.
For high-accuracy applications requiring traceable calibration,
verify the output parameters with a calibrated oscilloscope

.
Power requirements:
100 - 240 Volts, 50 - 60 Hz
Dimensions:
100 mm x 430 mm x 375 mm (3.9” x 17” x 14.8”)
Chassis material:
Cast aluminum frame and handles, blue vinyl on aluminum cover plates
Mounting:
Any. Add -R5 to the model number to add a rack-mount kit.
Temperature range:
+5°C to +40°C
1) -B suffix indicates IEEE-488.2 GPIB and RS-232 control of amplitude and frequency. See
http://www.avtechpulse.com/gpib
for
details.
2) For 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.
3) For analog electronic control (0 to +10V) of amplitude, suffix the model number with -EA. These units also include the standard
front-panel controls.
4) Indicate desired polarity by suffixing model number with -P or
-N (i.e. positive or negative), or -PN for dual polarity option.
5) The instrument may be used to drive resistive loads of less than 50 Ohms, as long as the maximum output current specification
is not exceeded. The rise and fall times may increase.
6) These instruments are provided with a basic calibration checksheet, showing a selection of measured output parameters. These
measurements are performed with equipment that is calibrated on a regular basis by a third-party ISO/IEC 17025:2005
accredited calibration laboratory. However, Avtech itself does not claim any accreditation. For applications requiring traceable
performance, use a calibrated measurement system rather than relying on the accuracy of the pulse generator settings.
