of the main output on a rear-panel connector. Requires a 50 Ohm load, if used.

GPIB and RS-232
control

:
Standard on -B units.
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 ± 10 ns. For high-accuracy
applications requiring traceable calibration, verify the output with a calibrated
oscilloscope

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 20% of full-scale, best results will be obtained by setting the amplitude near full-scale and using external attenuators on the
output.
3) Add the suffix -NC, -HN, -MHV, or -SHV to the model number to replace the standard BNC output connector with N, HN, MHV, or SHV connectors, respectively.
4) Add the suffix -M to the model number to specify the monitor output.
5) 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.
