Re; " Folks, in the CISPR 15 loop antenna there is a current probe specified. Can anyone direct me to a source please? I'm struggling. Thanks, Derek Walton L F Research"
There are adequate specification details in CISPR16-1-4 Annexe C, but no design info. there. I reckon that this "current probe" is a toroidal ferrite current transformer with a load resistor and possibly a calibration tweaking resistor. My company has made generally similar (but usually split-core) devices for other EMC applications and will be happy to design/make/calibrate a special for you if you cannot find an off-the-shelf item.
