H Field Probes, LNA, Differential Probes, and everything else!

It would be interesting to know, if someone already had successful experience with using ChipWhisperer and the H-Field Probe.

My Setup is:
H-Probe with LNA
Target Victim Board

I was trying to capture the key with H-Field Probe (and LNA) from the ATmega328P-PU. I tried several configurations in CWCapture, but didn't get any significant results.

Did anyone get good results with the same or a similar setup?

When I was testing with this, the waveform didn't look like much, but I was still able to get results. I'm on the road right now so can't upload an example, but I know there was another thread I had posted an image of the setup too:


This was with the older H-Field probe, I can try and recreate with the new one...
