Here is the pic of the power supply board in the LPB AM-25 unit. I apologize for the fuzziness, not a whole lot of room in there to navigate a camera for a clear shot, but you can see the components location and what should be there for a stock unmodified ps board.
Hope that helps.
Another big consideration in regards to meeting the specs for spurious emission limits are the in-band harmonics. Those MUST be at least 20db down from the fundamental.
With an ASMAX or C-CUFF exciter, that in-band harmonic is 45db down with the ASMAX and 30db down with the C-CUFF.
I use an HP 8590A analyzer and a Motorola RD2012 analyzer to check things…which I was informed are more than adequate to make proper measurements.
