Keysight Trueform Waveform Generators

Keysight Trueform Signalgenerators

Benefits of Keysight 33500 and 33600 Waveform Generators

  • High-precision arbitrary signals thanks to unique Keysight Trueform technology.
  • High signal integrity, low jitter, low distortion thanks to Keysight Trueform technology.
  • 1 or 2 channels, 20, 30, 80, or 120 MHz (sine).

Like any technology, the DDS technology used in most, commercially available signal generators has its limitations. Engineers with demanding requirements have had to either work around the limited performance or spend up to five times as much for a high-end point-per-clock signal generator. Keysight Trueform technology now offers an alternative that combines the best of both DDS and point-per-clock architectures, giving you the benefits of both without the limitations of either. Trueform technology uses an exclusive digital sampling process that offers unmatched performance at the same low price you've come to expect from DDS.
