R&S CRTU -rohde & schwarz service circular #1684

[g4wyz6]

When setting up the levels for Tx deviation, a dialog box opens stating that the deviation will be reset to 0.000kHz. If it needs to be extended read 'R&S service circular #1684'

I've Googled this term in-various permutations, but nothing useful was found.

Hello Mike,

this probably referred to a service bulletin on the old (now defunct) R&S Service Board.
A quick Google search suggest that might be its replacement? https://gloris.rohde-schwarz.com
Have a go at that.

Cheers, Marcel
