thanks,Azelio. Neubig kindly sent the location for the references.
Another good company, like the Wenzel site.

The then Hughes Aircraft had a nice hybrid (microelectronic ) version of this
idea produced in Newport Beach.

Subject: Re: [time-nuts] HP/Agilet counter 53131A (not 53151A) trigger
Hi Azelio,
Sorry, the counters are 53131A, not 53151A. The A and B inputs are specified
from DC to 225 MHz with a sensitivity of y20 mV (rms) up to 100 MHz, 30 mV
(rms) 100 ~ 200 MHz, and 50 mV (rms) 200 ~ 225 MHz.
The problem can be at either input alone. The problem is only in the range
30mV are -13dBm so maybe it is why the -20dBm is not a suitable level for
that input. I have the 53132A and the 53181A so I can test (with the RS
SML01). Is this problem new? Never tested before?
About the OCXO aging: OK, I'm interested in the development of a model that
can be general enough so
Isn't crystal aging marked by random jumps? perhaps lattice
rearrangement? Really hard if not impossible to model...

So it can't be done... the possibility to discipline an OCXO taking the
action from a suitable model should help in speeding up the adjustments and
avoiding the humps as seen in the Allan deviation plot.

My starting point is the paper by Neubig on the real vs. predicted aging:
experimenting with the model and try to cut it around the Morion or the
Oscilloquartz OCXOs.

characterize past aging, predict future aging, and
then correct the aging. The goal wasn't to turn a quartz
