in what way dies it? phase noise ? harmonics? standalone frequency stability?
Yes, all of those (specifically referring to the Trimble p/n 37265
OCXO used in the later Tbolts that we usually see as surplus).

Hi
Of course the point I made is not as useful as it might be.There are a ton of
Morions out there and very few Trimble OCXO’s outside of TBolts. I doubt
anybody is going to scrap out a working TBolt for it’s OCXO :).
Once you get them surplus, there is no reason to believe the Trimble parts
Any more details on this ? Ulrich

Ulrich,
I think my threads been taken over again. I keep writing about
modifications to the KS-24361 and the thread takes off in wild directions
about other things like Morion oscillators and TBolts. I believe your
question is to Bob perhaps on 1/f noise?

a EL2020 50 Mhz current opamp have a very nice 10 Mhz sine wave out. Any

Hi
Be careful when you do this.
A signal with harmonics 20 db down and sub-harmonics 30 db down will make a
fine reference input for a counter / signal generator / spectrum analyzer.
A signal with a 1 second ADEV of 5x10^-10 will look absolutely perfect on any
spectrum analyzer ever made. It

I agree with your comments.
For the test gear on the bench this will be very fine.

On the output of the crystal oscillator you will want to buffer it and then
do whatever you like. Its a sine wave and as I recall of fair level several
volts. I did see a bit of distortion on the sine wave. It can be obtained
at J8 the unpopulated jack.
Now back to putting it in its case.

That implies all Tbolts have the same OCXO... is that actually
true of most of the surplus ones ? Weren't there
Hi
For phase noise, they all are quite good, the newer ones are a bit better. For
ADEV and wander, the newer (post 2002) parts are the better bet.

Hi
So how does the 5 MHz get into the FPGA and / or CPU?
In order to discipline the OCXO and to generate the PPS, there must be a path.
If that path is independent of the 15 MHz (or 15 and 10) multiplier(s) then you
have a lot of things you can do. If either of the existing multipliers need

pick off a nice 5 MHz sine wave?
