Hi Bob,
thanks for the specs!!
For some reason this unit is slightly different though in it's specs:
It only uses +24V, no negative input provided by the Wavecrest PS. If you
are right, the -5.2V is only applied to the output to bias it, which is not
needed. The -5.2V pin is left floating

First of all. realize that the modulation bandwidth of the VCO has

Hi Stephan,
I have a surplus 100MHz Vectron OCXO from a Wavecrest DTS-2070
jitter-measurement system that was de-comissioned due to CPU memory failure.
The oscillator works great, and it was the main timebase in the $90K+ jitter
instrument, so I suspect it's the "best" OCXO they could buy
Poul-Henning,
Since the cost of the SC-10 gets pretty high if you go for all the best
options, I only specified one "A" grade parameter: 2 x 10E-12 Allan
variation combined with lowest phase noise. Otherwise the operating
temp is 0-50 C, total temperature stability is 2 x 10E-9 over 0-50 C,

Stephan,
If you can't find it explicitly I strongly recommend you to measure it. What
Poul-Henning suggested is about right, however you would like to have a FM
detector (not AM or PM) of sufficient bandwidth. A frequency sweep through
that should work well and display the amplitude responce vs fr
Stephan,
I'm still new at this subject and I'm not an expert, but here's what
I've found. The SC-10 oscillator from Stanford Research has this
paragraph in the manual:
"The EFC input exhibits a single-pole RC type response with a -3dB point
of about 3kHz when driven by a voltage source with a

If not in the public data sheets (the few OCXO's that I have state that info
in their sheets), you should be able to contact the manufacturer and they
can tell you. If they are no longer in business or it is a no longer
supported model, then you would have to manually test the OCXO to find the
band
Hi,
Many thanks to all the time-nuts that has answered my questions, which I
posted during the past year so, with such eloquence.
My question I have today is regarding the modulation bandwidth of the
typical OCXO. Previously, I was concerned with locking a 1PPS GPS output to
a 10MHz OCXO. T
