The AVR series provides peak outputs to 200 Volts, with rise and fall times of 2 or 10 ns. Pulse widths as narrow as 10 ns and as wide as 5 us can be provided.
AHF-1-B generates amplitudes to 250 Volts, with PRF to 100 kHz, duty cycles to 4%, and average output powers to 50 Watts. The pulse width is adjustable from 50 ns to 500 ns.
Instruments with the -B suffix include a complete computer control interface. This provides GPIB and RS-232 computer-control, as well as front panel keypad and adjust knob control of the output pulse parameters.
A large backlit LCD displays the output amplitude, polarity, frequency, pulse width, and delay. To allow easy integration into automated test systems, the programming command set is based on the SCPI standard, and LabView drivers are available. An Ethernet port for Telnet or Web-based control is optional.
A delay control and a sync output are provided on all models for oscilloscope triggering purposes.
The units can also be triggered externally using a TTL-level pulse.These models are protected from overload conditions (such as excessively high duty cycle or short circuited load) by an automatic control feature that limits the output power for as long as the overload condition persists.
Either output polarity or an optional dual output polarity can be provided. Polarity inversion in dual polarity -C units is accomplished by means of a two-position switch. -B units provide keypad / computer control of the polariy.
A DC offset or bias insertion option is available.
All models can also be supplied with voltage-controlled output amplitude options (0 to +10V). Units with the analog electronic control option also include the standard front panel controls.
