There is this sentence in CW505 Planar H-Field Probe - NewAE Hardware Product Documentation
For more details, see the H Probe Usage tip which includes a video with details.
That has link which should lead to tips and video, but gives 404: https://rtfm.newae.com/Tools/CW505%20Planar%20H-Field%20Probe/Images/H_Probe_Usage
I think this was the destination from original wiki: H Probe Usage - ChipWhisperer Wiki
There are few more in the docs in general (probably from migration), but I couldn’t list them all with wget --spider -r -nd -nv -H -l 1 -w 2 -o run1.log 'https://rtfm.newae.com/'
(doesn’t find all of them, maybe something like phantomjs or zaproxy would be better)
