How to measure the coherence bandwith and coherence time directly with an VNA or spectrum analyzer?

25 April 2017 0 755 Report

I need to determine the coherence bandwidth and coherence time of an NLOS situation, where measurements will be conducted in a reverberation chamber. I want to use a method of measurement from which I can directly get the data.
