Measuring SNR of IF signal after demodulating

Question asked by stanleysg on Feb 28, 2013
Hi all,

i am doing FM modulation, with carrier frequency 100MHz and IF signal 1KHz. Basically the IF signal will be generated using signal generator, and flow through the microphone, modulated with the 100MHz carrier and going to microphone output, and finally using N9010A to demodulate and provide reading of IF signal.

The problem is, how to measure  SNR of the signal, rather SINAD. I wonder how i can measure SNR using N9063A analog modulation application?

they only provide SINAD, without the SNR ratio.

by putting a marker on peak magnitude and noise floor seems unlikely too as i cannot have the SA mode under N9063A.

thanks if anyone can input any thoughts.
