Hi All, anybody have a recommendation for a RF demodulator/detector probe to use mainly with a signal tracer or sometimes an o scope? Would like it to have a BNC connector on the end for attaching it to my equipment. A quick search seems to find X1-X10 probes, not detector probes. TIA

Ron,
You up to making your own? I can post the [simple] schematic for the one that came with an Olsen KB-141 Signal Generator and Tracer.

Thanks fenbach but that’s exactly what I did. I bought some cables with a BNC connector on one end and redid an old probe replacing a capacitor and the diode with a 1N34!
