Avtech 14156, Instructions Manual

Page: 7 / 42

SPECIFICATIONS
Model 1 : AVRH-3-B
Amplitude (to R ≥ 10 kΩ): < 30 to 3000 Volts
Rise / fall times (20%-
80%)
2 :
≤ 100 ns
Pulse width (FWHM): 200 ns to 2.5 us
PRF: Internal trigger: 1 Hz to 1 kHz. External trigger: 0 Hz to 1 kHz.
Polarity 3 : Positive or negative or both (specify)
GPIB and RS-232 control 1 : Yes (standard on -B units)
LabView Drivers: Check http://www.avtechpulse.com/labview for availability and downloads
Ethernet port, for remote
control using VXI-11.3,
ssh, telnet, & web:
Included. Recommended as a modern alternative to GPIB / RS-232.
See http://www.avtechpulse.com/options/vxi 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 4 .
Propagation delay: ≤ 200 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.
Suppresses triggering when active.
Connectors: Out: SHV 5,6 Trig, Sync, Gate: BNC
Power requirements: 100 - 240 Volts, 50 - 60 Hz
Dimensions (H x W x D): 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
Temperature range: +5°C to + 40°C
1) Provides IEEE-488.2 GPIB and RS-232 control of amplitude, pulse width, polarity, PRF and delay. (See
http://www.avtechpulse.com/gpib for details).
2) For output coaxial cable lengths of less than 3 feet / 1 meter. Longer cable lengths will degrade the rise and fall times.
3) Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative) or -PN for dual polarity option.
4) 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.
5) MHV or HN output connectors can also be provided. To specify, suffix the model number with -MHV or -HN as required.
6) An adapter kit, consisting of an SHV PLUG to MHV FEMALE adapter and an MHV MALE to BNC FEMALE adapter, is available.
Add the suffix -ADPT1 to the model number to order this kit.
