Testing modulated signal parameters with spectrum analyzer

Question asked by ravoncat on Aug 21, 2014
I need to test analog modulated signals (AM, FM and PM)  however while I'm familiar with basic spectrum measurements this is the first time I've needed to measure modulated signals. I have a N9020A and an E4440A spectrum, and can get access to an E4407B, can anyone suggest a simple way to test some of these parameters?
Max Frequency deviation of Frequency modulated signal
Max Phase deviation of Phase Modulated signal
Frequency response of Frequency modulated signal
Frequency response of Phase Modulated signal

I figure the best way to test AM parameters is with an oscilloscope, but that won't work for FM and PM parameters.
