A replacement for this product is available:


Improve the standard phase noise performance of the PSG
The PSG equipped with Option UNR sets a new industry standard for microwave signal generator phase noise performance. Option UNR 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.

Typical applications
Option UNR 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.

How to upgrade
A customer installable upgrade kit does not exist for this option.


  • Industry leading phase noise performance - The improved frequency reference minimizes residual FM resulting in superior phase noise performance at offsets < 10 kHz from carrier. At 10 GHz carrier frequency and 1 kHz offset, Option UNR achieves over 25 dB improvement compared to standard phase noise performance. View specifications
  • Unrivaled technology leadership - Attain leading-edge frequency reference technology in a standard off-the-shelf microwave signal generator.
