A friend of mine has bought a just out of calibration R & S XSRM Rubidium
standard from one of the so called "recyclers" on Ebay.
Although the price was good, and it came with the off air receiver, phase
meter, and frequency divider, it looks to have been heavily decommissioned
with deliberate damage to the internal wiring and the rubidium lamp removed.
We've found the relevant manuals online and he's confident he can repair
the wiring but he still needs to locate a lamp.
If anyone has a working lamp available, or might know where one could be
obtained, please contact me off list.
He did comment that the lamp assembly looked as though it might accept the
lamp from an Efratom FRK, can anyone confirm this?
Alternatively, is there likely to be any risk of damage to the FRK lamp or
to the XSRM lamp driver if he tries it but it's not compatible?
