Checking Low Frequency Noise

Hello,

I recently had a customer ask how they might measure low frequency noise (hum) at 60Hz on a HP 8662A, at -80 dBc down from the carrier signal.

I discussed with several engineers and thought I would post here as well.

Is there a reliable and repeatable way to do this?
