Thanks. I've never found any noise sources that show up on the ESM1. I have
generated some on my own to test the ESM1 but it's good to know it can
detect noisy switchmode power supplies.

I am still curious though about how a device that obviously filters ~120kHz
still outputs noise in that vicinity. Their filter must not be all that
effective.
