Phase Noise Measurement

Test Description

This test measures the phase noise of an oscillating output using a spectrum analyzer. Phase noise can be measured in two ways: by directly calculating the spectrum analysis measurements, or by using a PSA's Phase Noise Measurement Personality and letting the output display the PN measurement in a Log-Log plot for any chosen frequency offset range.


Principal Equipment Involved

  • DC power supplies
  • Agilent E4448A PSA Spectrum Analyzer
