The AVIR series is designed for 200V applications requiring pulse widths from 2 to 1000 ns, at repetition rates up to 50 kHz. The AVIR-2 family is similar, but features pulse widths from 3 to 10 ns, with 1.5 ns rise times, and operation to 20 kHz. The -C versions provide 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 front-panel switches and oneturn controls. All models require 100 - 240V, 50-60 Hz prime power.
