John, You may also try a magnetic (or electric) sniffer probe by using it in an opposite direction.
Conventional way using the sniffer is to connect it to a preamplifier and an oscilloscope. The sniffer serves as a receiving antenna. ... The opposite way is to connect it to a signal generator - (caution about the power level), and make it a transmitting antenna. You may pinpoint this small antenna to any suspicious part on the circuit board to see if it brings about the system immunity problem.
