Hi All, My $.02 worth... I strongly disagree with what has been said regarding operation of output fuses. You may have a case for input fuses/circuit breakers. It is my belief that the purpose of this test, which is a cross referenced follow through to the design requirements now contained in GR

S11 is the ratio of the reflected voltage to the forward voltage on a transmission line. It is a phasor quantity, so it has magnitude and phase. The in case of a ferrite clamp, one would put the clamp over the center conductor of a transmission line, and then short the transmission line just aft

Agreeing with both, I wish to add that while the probes are very useful in locating the source and are not (very) useful in predicting the absolute level of far-field emission they may be also useful to predict relative far-field difference in emission, because with all other things equal the f
