The AVR-E family offers medium-to-high voltage pulses with very fast rise and fall times.
The AVR-E3 series offers a maximum amplitude of 100V, with 500 ps rise time, 1 ns fall time, and a maximum PRF of 50 kHz (or 5 kHz for the extended pulse width option).
The new AVR-E3A series also provides a maximum amplitude of 100 V but with a 1.2 ns rise and fall time, a 10 to 500 ns pulse width range and a maximum PRF of 200 kHz, with a maximum duty cycle rating of 2%.
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. To allow easy integration into automated test systems, the programming command set is based on the SCPI standard.
The -C versions provide output pulse parameters similar to those of the -B models, but do not include the GPIB or RS-232 interfaces (i.e. no computer control or LCD display). The output parameters are controlled by frontpanel range switches and one-turn vernier controls.
All 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 exists.
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 or menu. A DC offset or bias insertion option is available.
“-C” models can also be supplied with voltage controlled output pulse width and amplitude options (0 to +10V).
Units with the electronic control option also include the standard front-panel one-turn controls.
All models require 100-240 V, 50 - 60 Hz prime power.
