please check the test result (with battery power)

Very fine post

We have same Wenzel, compares well to the HP and other OCXO

But your ask price seems in  error?

Just a note

seriously ??  cheap from 75$ usd up to +/- 300$ ?   

put the aging sheet too ...

Those look like Wenzel Small Fry OCXOs, not "ULN" parts.  They're still good oscillators but it's fair to call the pricing into question, given that there are a lot of other parts with similar performance.

ULNs look like the one on this board:


Not super common.  They're about $2K-$3K brand new.

Another thing to note about these oscillators is that the 500 series part numbers have been modified to suit a particular customer's needs.  Standard units use part numbers that start with 501.

Wenzel won't give any info what has been modified so, in this case, the datasheet for the Small Fry oscillators can only give general guidance.  For example, this oscillator has five leads while the standard Small Fry only has four.  This could be a good thing, but has anything else been changed?  Was the change an upgrade (e.g. lower aging), a downgrade (e.g. smaller temperature range), or just a change (maybe the extra lead is an oven monitor).  There's no way to tell.

 Wenzel we have was surplus, silent key or ham flea.

Aging: DIY with my equipment and comparison vs a Leo Bodanr GPDSO and  four  classic HP OCXOs.

no, some of them as retail will print "ULN" in the top, but, most of them just customized OCXO, never print the "ULN" or "BT ULN" signs.

I can tell the customer about the pinout, it is no problem.

Do you have anything for 10MHz with better than -120dBc/Hz at 1Hz and -170dBc/Hz far out?

Have a look at https://kvg-gmbh.de/en/product/o-30c-hf/
Looking at the digikey prices of the similar/rebatched Taitien NA-10M-68xx you should expect the double of what is asked for those here.

They cost €1300+ in small quantities.

my current using is, you can check the noise floor of the above picture.

I never see any phase noise tester/Analyzer using the Taitien Quartz as reference, the aging rate is 1ppb/day (after 30 days), the Wenzel is 0.25ppb/day (after 30 days).
