I want to buy a near-field probe to scan the interference points of PCBA with a spectrum analyzer. How should I choose this probe? For example, if the product is 1-10M, the interference point may be several megabytes, hundreds of kilobytes, or tens of kilobytes. What are the precautions for use?

The sensitivity of your own spectrum analyzer is very high, so you can choose a probe with a slightly lower sensitivity
of 1-10M. The interference point may be several megahertz, hundreds of kilohertz, or tens of kilohertz.
Buying a near-field probe set will include several different types of probes.
