Fluke 294-U Arbitrary Waveform Generator and Manager, 100 MS/s, 4 Channel

The Fluke 294-U is a 12-bit, 4-channel arbitrary waveform generator operating at 100 MS/s with a true variable clock architecture that minimizes jitter and enables advanced waveform linking, looping, and sequencing. It generates arbitrary waveforms, standard functions, pulse trains, swept signals, DTMF tones, and modulated signals for electronic testing and design applications.
