So, you've moved into the frequency domain but what are you looking for from your spectrum analyser. Intuitive use, a built in fundamentals guide, easy connectivity to the internet, absolute measurement specs, easy connectivity? What do you say?
What I want from a spectrum analyzer are high frequency stability, high dynamic range, low noise floor, low internal spurious, good filters and high accuracy.
Remote control options are nice for making automatic measurements.
Why connect to the internet? If I want others to share my test results I send them an Email.
In addition to JVDBERG's comments, I would like to add analysis tools, and storage capability for both the raw data and the resulting spectra. To be fully useful, you need a flat response curve for the spectra you are measuring or at least the ability to compensate for different frequency sensitivities.
