The Keysight 33622A is a 120 MHz, 2-channel Trueform arbitrary waveform generator (AWG). Leveraging Keysight's Trueform technology, it offers true point-by-point arbitrary waveform generation without the skipped points or aliasing typical of older DDS generators. It delivers a 1 GSa/s sample rate, 14-bit vertical resolution, and exceptionally low jitter (< 1 ps) for precise signal generation across a variety of test and measurement applications.
