Key Features & Specifications

Signal analysis

  • One-button measurements for analyzing phase noise in frequency domain (log plot) and time domain (spot frequency)
  • Compatible with phase noise measurement personality in Keysight ESA spectrum analyzers
  • Runs inside CXA signal analyzer


  • Log plot: Phase noise view in frequency domain including DANL floor and integrated noise measurements along with spurious table
  • Spot frequency: Phase noise view in time domain including carrier frequency drift measurement
  • Monitor spectrum: Easy-to-use simple spectrum view for a quick check of your signal

The W9068A phase noise measurement application for the CXA 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 CXA signal analyzer 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
