The AV-151 series is a family of high-voltage (or, for the AV-151F, high-current) function generators and variable-gain amplifiers. All models include both an internal oscillator that can generate sine, triangle, and square waves, and a variable-gain amplifier mode, which permits generation of more complex high-voltage
waveforms. Avtech offers the AV-151E family, which provides a peak output of +/-25 Volts to loads as low as 20 Ohms, at frequencies up to 20 kHz. The -C versions provide output 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) or the pulse mode feature. The settings are controlled by front-panel switches and dials.
