I am trying to determine which specifications are used that set the
amplitude and frequency accuracies of a site source that in turn is
being used for performance testing inside of an EMI chamber.

I am soliciting information regarding EMC standards that pertain to
testing Hall-Effect Sensors for Safety Restraint Systems in the
Automotive market. Anyone familiar with these specifications written or
being written by any of the Big 3 are invited to contact me directly.
Sincerely,

I am soliciting opinions from anyone who has attempted using an antenna
carousel that aids in doing automated EMI measurements under CISPR 25.
The CISPR 25 specification provides requirements in terms of spacings of
the antenna elements from the walls of the room, size of the room, use

I fully agree with Bob Wilson's comments concerning a good solution.
It is only when marketing becomes responsible for its decisions will it
provide marketing information that is truly useful.

Another important point to consider on safety margins is how the site
performed for Normalized Site Attenuation (NSA) when applicable.
A +/-4dB variation is the maximum allowable for NSA based on the premise
that 1.5 dB is attributable to the site uncertainty and 2.5 dB is
attributable
Paolo,
My experience has been that if it is an Optical Isolation Circuit, the
actual RF isolation is usually far from desirable because of undesirable
capacitive coupling that occurs within the transmit and receive
circuitry.
I would suggest that you determine if undesirable coupling occurs

With respect to your radiated emissions dilemna, useful information
would be the clock speeds, cable lengths, and worst-case mode of
operation at which emissions are the highest. Generally, if you invoke
the divide and conquer rule, it should be an easier matter pinpointing
the dominant
