This link shows the light from a rubidium spectral lamp.
Its appearance is quite similar to the rubidium lamps used in various
rubidium standards.
There can be a slight bluish cast also, especially at low temperatures as
the lamp warms up.
I'm not familiar with the R&S but depending on the design there may not
be any channel to view the lamps discharge!
Now I know where to look when the device is disassembled. It is not
possible to see when assembled.

This is the colour I have. Notice that it is a Rubidium/Xeon mixture.
I have now adjusted the OCXO and the loop pulled in every adjustment
nicely, so the loop is safely closed. Only C-field adjustments and ADEV
measurements remains. :)
Thanks for everyone contributing! :)
Cheers,
Magnus
