The 85671A is scheduled to be discontinued on 1 November 2009. The N9068A phase noise measurement application with X-Series signal analyzer (for RF/µW applications) or PSA (E444xA) with Option 226 are the recommended replacement alternatives.
The Keysight 85671A phase noise measurement utility is a downloadable program that transforms your Keysight 8560 series spectrum analyzer into a phase noise tester. The 85671A removes the work in performing phase noise measurements.
The 85671A utility eliminates the time-consuming task of hand-drawing phase noise plots. To measure oscillator phase noise, you no longer need to spend time manually tuning your spectrum analyzer to multiple frequency offsets. You can quickly and easily generate graphs of phase noise (dBc/Hz) versus log offset frequency or integrate the results over a band of interest for degrees or radians RMS.
