This is just a short note to let all my friends on the EMC-PSTC list

Tony:
I don’t want to appear to be overly picky, but your diagrams don’t show “what
happens to the emissions,” but rather show how the QP detector receiver “sees”
the emissions. In a dithered, or frequency hopping clock, the clock hops to a
frequency, dwells there for a short moment and
Don:
I think that the spread spectrum clock works because of both the
receiver bandwidth and the detector function.
For instance, imagine a pure CW clock signal, and it is being hopped
around in 1 kHz steps, all in the range of 10 kHz. Now imagine that a
receiver with a 1 MHz resolution
But Albert was a Theoretician, not an Experimentalist.

Don't forget to include a low-pass filter for the AC powerline where it enters
your shielded work area.
Another alternative might be to find a used TEM or GTEM cell. It will give you
shielding, plus you can also do radiated emission and immunity pre-scans too.
