More please!

With all that kit you have in your lab you have the opportunity to demonstrate things that most of us have only read about in books.

The length of the phase noise video was OK and the technical content was about right. The audio quality was VERY good, slightly clipped with just the right bandwidth.My only problem is that you talk a little too fast and not all of us have English as our first language. Sometimes I had to rewind a passage until I understood it.

I don't think he talks that fast. It can become annoying for others when someone talks slowly. Maybe the adjust playback speed feature on youtube will work for you as it can slow down the video and maintain correct pitch in the audio.

YetAnotherTechie:
Can the cross correlation technique be implemented with two separate and different spectrum analyzers, and some matlab code of the captured signal? or does the signal have to be captured at the exact same time by the two then processed? I have a CMU200 and a FSEM21 spectrum analyzer available and don't mind waiting...

mawyatt:
Don't think it would work as the signal of interest must be split and experience almost exactly the same path channel characteristics. Delays, time skew, amplitude and phase characteristics need to be identical for the cross-correlation to work. Any variation would appear uncorrelated and tend to average out along with each channel phase noise, and not contribute to the eventual "signal" growth during averaging.

Best,
