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.
