The instruments in the Avtech AVB2 series of high-voltage monocycle generators provide peak-to-peak outputs of 200 or 400 Volts for frequencies in the range of 10 to 200 MHz. The AVB2-TB offer center frequency ranges of 50 to 100 MHz. The -C versions provide output pulse parameters similar to those of the -B models, but do not include the GPIB or RS- 232 interfaces or LCD display. The output parameters are controlled by front-panel range switches and one-turn vernier controls.
