And at its max frequency of 1 GHz it will be all of 20 Hz off! 

OMG for sure.   :-)

Subject: [time-nuts] I am a nut

I just got an HP 8920B service monitor to replace what I had before.
It has the High Stability oscillator option. After running the self
tests, I was doing a quick check of the internal reference. With my
frequency counter locked to a GPSDO, I see that the 8920B reference is
0.2 Hz high. OMG! I'd adjust it, but this thing came calibrated and I
don't want to mess with it quite yet.

Just thought I'd share my obsession :-)
