[time-nuts] 5370B OCXO

[Bob Camp]

Hi

The OCXO in the 5370B is a 10811-60111. The only added spec on it is a 1x10^-11 ADEV spec at 1 second. By modern standards that's not a real tight spec. There are other 10811's with tighter specs on them at 1 second. My guess is that it was not a real tight spec for the 10811 to hit. 

The short term would appear to contribute to the total error on the counter. Why not put a better oscillator in it?
