Measuring Frequency Accuracy with a Spectrum Analyzer - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

I'm trying to measure the frequency accuracy of a modulator using an Anritsu MS2721B. I've never made this measurement with a SA before. I'm feeding the modulator and SA a GPS 10MHz reference frequency. The modulator is set to CW mode. How do I can configure the SA to (correctly) measure the frequency of the CW? And how can I set it to record this measurement over a period of time, say 30 minutes?

One would have to check the frequency resolving power of the Anritsu MS2721B. You should be able to find this in the Equipment Specification for the instrument. From there it is a matter of the display resolution per pixel i.e. RBW bucket it is able to resolve for display. That is your level of frequency resolution. It is poorer than a frequency counter with a high or ultra stable freq reference source.
