An arbitrary waveform generator (ArbGen) is an extended function generator (FGen/FuncGen) that can generate freely programmable signals in addition to standard waveforms such as sine, square, triangle or trapezoid. In general, the voltage/current as well as the frequency/duration of the output signal can be freely adjusted.
The arbitrary waveform generator can be used very flexibly and is therefore part of the basic equipment of every modern test system.
