I dowse, that a running frequency, used for a signal, governs any other frequencies. Any EM interference coming out of the device, has its frequency blocked, by the running one..
Horsehockey.....that board could be radiating any (or many) freq. from DC to Daylight. That's a fact.
Test: Set the board on a 1M height table inside an anechoic chamber, and power up the board. Set antennas at 3M, then run a scan from 1 khz to 10 ghz. Then you will actually know what that board is radiating.
