The Keysight 33521B is a single-channel, 30 MHz waveform generator delivering high-fidelity signal generation through Trueform technology. This benchtop instrument generates standard waveforms, arbitrary signals, and modulated outputs with harmonic distortion and jitter performance. The 250 MSa/s sampling rate and 16-bit resolution enable precise, repeatable signal creation for design validation, circuit characterization, and research applications.
