The N9068A phase noise measurement application is one in a common library of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements and software. Transforming the X-Series signal analyzers and MXE EMI receivers into a phase noise tester with convenient one-button operation, automating the measurement procedure.

Phase noise measurements

  • View the phase noise from frequency offset 1 Hz
  • View the phase noise behavior of the signal under test across decades of offset frequencies with the log plot
  • Use AM rejection in the log plot so that you observe only the phase component
  • Characterize phase noise related behaviors from different angles for various applications with multiple markers with various marker functions
  • Signal Tracking provides a simultaneous view of phase noise and delta frequency in time domain
  • Working with N9030A PXA and external mixer, it enables phase noise measurements with the carrier frequency up to 50 GHz and beyond
