Andy,
I have not used 62493 so I'm not familiar with the details; I
looked it up on the IEC website to get an idea as to what it covered and
reported their summary.
In reading thru this I see several points here.
1) The broad band radiation up to 300MHz
I agree. One particular point is keeping a trace connected to an
inverting input very short, even if that means including a low-value
'stopper' resistor close to the chip. That point has quasi-infinite
sensitivity but infinitesimal impedance only within the op-amp pass
band. Above the
And examples can be even more strange: we had DC-DC converter modules
failing to work properly because one of the converter's power pins
feeding an internal linear regulator picked up noise from the same
converter.

That should be warned about in the data sheet. Internal EMC problems
tend to be rare, which is good, but because they are rare, there
should be warnings if they can occur.

Hi Doug,
It was great to chat with you.
Here is a brief summary of the technical details we spoke (Doug, correct
me if I cite something incorrectly).
Staying with the question how could someone show and demonstrate the
amount of current the oscillator pumps into the circuit, there are a
