Hi Ken,
Ahh the emissions analogy to the immunity tests? Hey - why not?
After all there are plenty of conditions that arise NOT as an
EUT problem but rather
radiators.
The same could and should be applied to a cable-bundle emission requirement.

Charles,
I applaud your integrity! You are right to insist on maximization of
cable placement when performing emissions testing. The ANSI document
does indeed call this out, and the cable placement, as well as the
peripheral equipment placement, should be maximized, of course while
staying within

Hi Charles,
I always made it my responsibility (the owner of product) to ensure that the

I find that most lab techs won't remind you of this, once you have arrived

When the standards changed to move the EUT and peripherals to the back edge of
the test table, cable maximization was left mostly up to gravity with the
cables being draped as they fell. Most test facilities do not go any further
than that. I have seen OEMs that go so far as to do cable
Charles,
I maximize the cables anytime I run radiated emissions or conducted
emissions tests.
