[time-nuts] Austron 1250A ADEV Hump

[AC0XU (Jim)]

Time Nuts:

I have a few Austron 1250As. One of them has an ADEV with a large hump at around 50 secs time scale (2E-11). Using a 53230A counter, I can convince myself that I can see the frequency go up and down at around that period.

I guess that this is an oscillation in the oven circuits.Anyone have an idea whether this is curable and how?

Thanks!
Jim
