Racal Instruments 3151A

The Racal Instruments 3151A is a VXIbus waveform generator housed in a single-slot, C-size module that combines function generation and arbitrary waveform synthesis. Operating at up to 100 MSa/s with 12-bit vertical resolution, it delivers standard waveforms—sine, square, triangle, ramp, and pulse—alongside custom arbitrary waveforms. The instrument provides 512 KB of segmentable waveform memory supporting up to 4096 different waveforms, enabling flexible stimulus design for complex test scenarios.
