House standard should be pretty close as it's a Trimble Thunderbolt GPS. However, I don't *think* that is the culprit as thjis is just "close to" 10MHz, rather than "spot on".
So yes, oscillation is likely. Regards, David Partridge -----Original Message----- From: volt-nuts-boun...@febo.com [mailto:volt-nuts-boun...@febo.com] On Behalf Of J. L.

How close to 10.000 000 000 MHz is it? 100 mV P-P is fairly substantial. Otherwise, is it oscillating? Good luck.
