The Fluke 291-U is a single-channel arbitrary waveform generator delivering 100 MS/s sampling rate and 12-bit vertical resolution for high-fidelity waveform creation and simulation. This instrument combines arbitrary waveform, function, pulse/pulse train, sweep, trigger, tone, and amplitude modulation capabilities in one platform. Waveform management is handled through the included Waveform Manager Plus software for Windows, enabling seamless creation, editing, and storage across front panel, RS-232, USB, and GPIB interfaces.
