Key Features & Specifications

  • Up to 10 dB improvement compared to standard phase noise performance
  • Low close to carrier phase noise


Improve the PSG phase noise performance

Option UNX sets the industry standard for microwave signal generator phase noise performance. Option UNX replaces the PSG standard internal frequency reference with a high performance internal frequency reference that improves the close-in phase stability to provide superior phase noise performance at offsets less than 10 kHz from carrier.

Lower close to carrier phase noise than our previous enhanced phase noise option UNR

The ultra low phase noise Option UNX provides 5 to 7 dB lower phase noise at offsets from carrier of less than 2 kHz than our previous option UNR. View phase noise plots at four frequencies

Typical applications

Option UNX is recommended for signal generation applications that require spectrally pure signals and/or outstanding modulation accuracy. Typical applications include LO substitution, low-jitter clock stimulus, blocking/interference signals, stimulus/response measurements close to carrier, and high-order digital-modulation-format (e.g. 128 QAM, OFDM) signal generation.

This option can be added as a product upgrade.
