A tangential issue: those who rely on that algorithmic process often don't
know why certain things are required and others left unsaid. I've see a
manager forbid using a high-pass filter during CE testing because it appeared
nowhere in a standard's setup drawings. Demonstration was required!

Bingo. Clearly another driver for inserting MU where it doesn't belong
is a
desire to replace the need for competent personnel with an algorithmic process
that works for any personnel. But the same personnel who don’t know how to
properly perform the test will also not know how to run the algorithm. Hence
Mr. Walton’s observations on how poorly MU is executed in reality.

I think I would only add that while measurement uncertainties for EMC is
nebulous at best, at the same time we do not want to get into the habit of a
slam dunk mentality of ‘oh, just a number, it doesn’t matter.”
That is why Derek’s statement of “What’s really needed is a competent
individual with adequate equipment” is so important. Where electromagnetic
compatibility is concerned, competence of the engineers doing the measurement
is probably much more importa! nt than uncertainties. I know that one of the
biggest benefits to testing in the radio approvals industry is competence of
test personnel.
Compliance does matter and the best way to keep unneeded uncertainties
out of
the EMC measurement industry, is to keep competence of test personnel in.
