Apologies if this is not the right place to ask…

I was wondering if TinySA would help to look for sources of potential radiated EMC problems with a NF probe. I imagine setting it up, making changes to a design and looking for relative improvements.?

I am thinking about embedded electronics designs rather than specifically RF projects.?

thanks.?

Yes,
One of the early testers used it to find leakage paths through an EMC shielding.
I made a crude NF probe and used it to check for radiated EMC.
Is the sensitivity is not enough in low mode you can add an LNA as shown here:?

? 1. Ensure you maintain probe positioning between circuit changes for accurate comparison.? Also, if you are narrowed in on a specific problem frequency ensure you widen your scan after fixing that frequency. Fixing one frequency can sometimes have unintended consequences at another frequency.

? 2. The hand probe detects emissions in the near field and, for compliance testing, you may sometimes wind up chasing ghosts that are not seen in the far field with an antenna.
