    Can anyone recommend some basic equipment to "troubleshoot" radiated emissions failures? Or to "predict" possible sources prior to testing?

    spectrum analyzer?
    old rabbit ear/bowtie antennas?
    e/h field probes?
    CM current probes?

    On a 48VDC product I had a failure in the 36 to 47Mhz range that was solved by a simple addition of clamp on reffites but just want to see if I can move past the band-aid fix and find the source.

    Small diameter (~ 1" or less) loop antennae that connect to the spec an. to help zero in on radiators

    Can probaly make some yourself, check google.
