The AVR-E family offers medium-to-high voltage pulses with very fast rise and fall times.
The narrow-pulse AVR-E4 series can generate 100V pulses with pulse widths variable from 1 to 5 ns, at repetition rates to 100 kHz.
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, frequency, pulse width, and delay.
A delay control and a sync output are provided for scope triggering purposes. The units can also be triggered externally using a TTL-level pulse. Either output polarity or an optional dual output polarity can be provided. Polarity inversion in dual polarity units is accomplished by means of a two-position switch. A DC offset or bias insertion option is available.
