FreeLists / si-list / [SI-LIST] Re: Looking for Spectrum Analyzer info

[Jochen Feldhaar <feldhaar@xxxxxx>]

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

Jochen Feldhaar DH6FAZ
