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. AV-153AH-B can operate into loads of 1.2 k and higher, with average output powers as high as 50 Watts. 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 parameters.
