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-4 family essentially combines the AVIR-2 and AVIR-3 technologies to offer pulse widths from 4 to 200 ns, in two ranges (4 to 10 ns, and 10 to 200 ns). The -C versions provide pulse parameters similar to those of the -B models, but do not include the GPIB or RS-232 interfaces.
