Learn more about how different instruments measure phase noise

Phase noise can be measured using traditional spectrum analyzers as well as dedicated phase noise analyzers. This whitepaper explains the difference between these two methodologies and in particular, how the cross-correlation method improves both the sensitivity and accuracy of phase noise measurements.

You will learn about:

  • The spectrum analyzer method
  • Normalization and shape correction
  • The cross-correlation method
  • Cross-correlation gain
