Tuned RF Level Measurement Poll

[mdbuike]

We need to also mention that the MMR takes longer to measure AM/FM Mod. at least that is my experience. 8902 takes a much faster reading.

Have you looked at the cal procedure for the MMR?  How do they ceritify the AM/FM calibration?  Implied?

Maybe an old argument..but I'll use the 8902A

Agilent claims that if the Tuned RF Level and Spectrum Analyzer portions of the instrument pass, all other parameters are "guaranteed by design". This makes sense to a certain degree being as though you can measure modulation depths (AM) and rates (FM) on a spectrum analyzer. I'm assuming that the instrument uses the spectrum analyzer circuitry (amplitude and frequency markers, span, etc.) to compute the modulation and convert it to a easy-to-read numerical display via the Measuring Receiver Personality option.

I have been trying to get AFMETCAL to tell me how AM/FM and even TRFL measurements are made.  No such luck.  They can't tell me what specifications guide is the correct one.  Been told June 2008, even the lovely spreadsheet they made.  So VERY frustrating.

Whats a MMR?  Who makes it.
I've got a Rhode & Schwarz FSMR with sensor head-it's very fast in tuned RF compared to the 8902A.  The part that impresses me during verification vs. the 8902A is that an arbitrary waveform generator is used to make actual AM & FM signals of a known level, the 8902A seems like it's all relative measurements.
It's furfigtestin!

Its a fancy spec an that replaces the 8902A ( or supposed to ).
