Hi Edgardo
The original PRFS standard used an FRS module so I suspect yours will too,
but a quick check when it arrives should confirm for sure.
The VRFS standard, which is a VXIbus unit, also uses the FRS, although the
FRT standard used the FRK module.
A quick Google search on Efratom manuals will provide plenty of information
on the modules themselves and the manual for the original PRFS is here....

The FRT manual and calibration instructions are here....

The VRFS is obviously very different mechanically but it's possible there
may be some circuit similarities, although no promises:-), so if you'd like
a copy of that manual it's at...

Dear Group,
Good morning. I recently got an Efratom PRFS202 Portable Rubidium
Frequency Standard. Mint condition. Locking in 3 minutes or so. Outputs OK, both
sine and TTL.
It seems a simple straightforward instrument. Still I would like to know
if anybody has a manual available for it. I tried looking for it online and
no luck so far. This unit was marketed also using the Datum brand. Same
model.
Anybody has at least a brochure or general specs for this particular unit?
Any experience or comments for this unit? Got it at a decent price
considering the lack of information.
As always, your kind comments are surely welcome.
Thanks!
Regards,
Edgardo Molina
