The AV-153 series of function generators provides high voltage (up to +/-200V), high power (as high as 90 Watts) waveforms at frequencies as high as 300 kHz. The AV-153B-B ioperates to 50 kHz and provides amplitudes to +/-135 Volts, and average output power to 40 Watts. Instruments with the -B suffix also 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 parameters.
