(250 mA max) to back panel solder terminals.
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.

Propagation delay: ≤ 160 ns (Ext trig in to pulse out)
Jitter: (Ext trig in to pulse out) ± 35ps ± 0.015% of sync delay
Sync output: > +3 Volts, > 50 ns, will drive 50 Ohm loads
Gate input: Synchronous or asynchronous, active high or low, switchable. Suppresses triggering
when active.
Connectors: Out: SMA, Other: BNC
Power requirements: 100 - 240 Volts, 50 - 60 Hz
GPIB and RS-232 control 1 : 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, after 10 minute warm-
up:
Amplitude: Typically ± (3% of setting) ± (2% of maximum).
Delay, Period: Typically ± (3% of setting ) ± (5 ns)
Pulse width: Typically ± (3% of setting ) ± (2 ns), at maximum amplitude. As the
amplitude is reduced, the pulse width may shift ± 5 ns. For high-accuracy applications
requiring traceable calibration, verify the output with a calibrated oscilloscope 7 .
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
Temperature range: +5°C to +40°C
1)
-B suffix indicates IEEE-488.2 GPIB and RS-232 control of amplitude, pulse width, PRF and delay (see http://www.avtechpulse.com/gpib ).
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) Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative) or -PN for dual polarity option.
4) The -OS option adds an internal bias tee circuit to the output, allowing an externally-generated DC offset (±25V/250mA max) to be added the output
signal. The -OT option includes the -OS function, and adds the ability to generate a ±5V/100mA offset internally (controlled from the front panel, or by
computer command).
5) Fall time increases to < 3 ns for pulse widths less than 15 ns.
6) A 50Ω load is required. Other loads may damage the instrument. Consult Avtech ( info@avtechpulse.com ) if you need to drive other load
impedances.
7) 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.
