"standing waves. If you happen to have a fairly long cable, it is possible
you can identify certain nodes and nulls along its length based of the 1/4
wavelength of the emission. If it is broadband RF however, you may not be
able to diagnose this."
A sooner, rather than later plan is to build a chamber of some sort probably
an adequately sized TEM cell and use an SDR receiver to study items within
across a wide range. I have Singer and Marconi spectrum analyzers, but I am
finding them bulky (Singer, 220#) and limited compared to some of the SDR
work I'm seeing out there.
I think with the SDR and adequate probes I can trace noise to a fraction of
an inch or individual traces.
