Arbitrary waveform generator
open-in-new
<p>An arbitrary waveform generator (AWG) is a piece of <a href="/facts/Electronic_test_equipment/0z8CCX04">electronic test equipment</a> used to generate electrical <a href="/facts/Waveform/yAskMREw">waveforms</a>. These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). The resulting waveforms can be injected into a device under test and analyzed as they progress through it, confirming the proper operation of the device or pinpointing a fault in it. </p>
