The AVIR series is designed for 200 Volt applications requiring pulse widths from 2 to 200 ns, at repetition rates up to 50 kHz.
The AVIR-1 family provides output amplitudes continuously variable from 0 to 200 Volts (into 50 Ohms), pulse widths variable from 2 to 5 ns, and 0.8 ns rise times. The maximum pulse repetition frequency is 50 kHz.
The AVIR-2 family is similar, but features pulse widths from 2 to 10 ns, with 1 ns rise times, and operation to 20 kHz.
For wider pulse width applications, the AVIR-3 family offers 10 to 200 ns pulse widths with 2 ns rise and fall times. The AVIR-3A-B is similar, but
offers faster rise and fall times of 1 ns.
All models include an internal oscillator variable up to 50 kHz (AVIR-1 family) or 20 kHz (all other families) using the front-panel controls. A delay control and a sync output are provided for scope triggering. All models can also be triggered
externally with a TTL-level pulse.
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.
