With most sensitive equipment, a set of low insertion loss, high bandwidth
DC blocks and bias tees are a must. You typically need them in sets of at
least 2. I recommend 4 of each at a minimum.

Hi Gary,
you have made a big time hit!
A spectrum analyzer is the best instrument for a LOT of measurements!
(yeah!)
BUT: Never connect DC to the input (even if it says it's OK...)
Measuring power switching noise is mainly a coupling problem - how to
connect the input to the SPA...
any AC way will do, as long as the appropriate frequency is OK.
I am sorry if this is a short reply, as I am writing a book on the
subject presently, but I need to know some more specific parms to give
better advice.... hehehe
Best Greetings
