Need Oscillatek 8032 OCXO pinout/specs
« on: May 09, 2020, 10:12:41 pm »
Hello,
i have a vintage bit of kit that i'd love to test out but i can't find the pinout or specs:
An Oscillatek 10.000MHz OCXO
P/N 282376B
model 8032
My unit also has a Scientific-Atlanta PN: 285603
It has the 10Mhz coax output and a 7-pin connector, 2 of those have soldered and shrink-wrapped cables that are cut, i guess those are the power supply but i have no idea the voltage needed either(i could start cranking up until i get an output)

This OCXO was pulled from scientific-atlanta satcom datalink systems (the ooold ones that worked at RS232 speeds and were 3U high rack units, plus big 2m diameter antennas with ORUs)

All i can find is ebay listings of it and it appears the company changed names as well to VI-OLATHE, but absolutely no info on its performance or pinout(and i don't have the gear to really characterize the stability/phase noise/phase stability of this)

Did you see the one on ebay that includes a photo of the spec sheet?   :)

oh wow i did not see that!.

excellent!

so it's 12vdc, good

phase noise:
-128dbC/hz @100Hz
-135dbC/hz @300Hz
-145dbC/hz @1 to 10Khz

stability: +-1 x10^-9/day (i guess that's Hz) and +-3x10^-8/month
temp stab: +-2x10^-8 0 to 60°C
to supply: +-10x10^-10/1% supply change

settability: +-1x10^-8 (what's settability?)

but the subharmonics are not visible due to a crease in teh paper

now, ¿are those values good for modern standards?
