The Keysight 83630A synthesized sweeper is the standard of excellence for applications requiring the high performance and accuracy of a synthesized source and the speed and versatility of a sweep oscillator. Synthesized broadband frequency coverage and precise 1Hz frequency resolution (Opt 008) are generated by indirect synthesis, enabling the Keysight 83630A to achieve low single-sideband phase noise performance. It delivers excellent harmonic performance with harmonics at least 50dB below the carrier from 2.0 to 26.5GHz.
