[time-nuts] Efratom PRFS202 Portable Rb Freq. Std. Manual

[GandalfG8 at aol.com]

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
