Hi
For most OCXO’s most certainly not. The typical OCXO improves on ADEV as it
runs. That said, a good OCXO should have a 1 second ADEV
of at least parts in 10^-12 rather than 10^-11. A 5370 should have a floor at 1
second of around 2x10^-11. You may be measuring your counter

I've had a specific GPSDO running for some time now, and I notice that the
noise at tau 1s has gotten worse as the retrace flattens out. In this case,
the ADEV was about 3.6E-11 a month or so ago, and has now gone up to about
8.5E-11. (Measurements performed by a 5370A against a PRS-45A Cs st
