I've seen more than one (old) GR 1383 Noise Generator on eBay for <$30. The
one I bought works just fine. They have a calibrated output with a step
attenuator & output meter. The noise flatness is specified from 20Hz to
20MHz. I suspect there are other cheap sources along the same line.
While this may soune like overkill, it will provide a know level of PM & be
easy to repeat.
