Cross correlation is one of life's few free lunches, but you do have to wait
for it to work. Magnus is correct in that you can get a 3 dB advantage in
noise reduction per sweep, but that only applies to the first sweep.
Agreed. Did not mean to say anyt

Hi Magnus,
Thanks a lot for the concise and very clean explanation.
You are welcome!
The cross-correlation part between the two signal was clear enough in
my head but I didn't really see how it would achieve much gain. I

Hi,
I've heard and read some documents about using cross-correlation using
two distinct reference oscillators when trying to measure the phase
noise from a source to reduce the influence of the reference
oscillators phase noise.
Unfortunately, it's still not exactly clear to me how it works ...
