Jeff,
You have a 250MHz VCXO
+/100 ppm deviation for +/-5V
12V supply
Here are general specs:

It is a low end OCXO - uses AT cut crystal. 15V @ 300 mA. Warm-up time is
6 minutes max for .1 ppm. Other specs as indicated in previous emails.
Has NO EFC.

I agree, it looks like the W1AW 40 M measurement was off.

Jason,
Post the part number and / or pictures. I have some old CTS catalogs
- possibly the information will be there. Their web site is very

I suspect the current SRS rb oscillators on EBay are pulls from the
Symmetricom TimeSource 2700 (especially since the same seller is
selling a TS 2700 board). There are a couple of TS 2700s on EBay -
starting at $499. It steers the rb based on CDMA signals. It was
marketed as an alternative to GP
