I apologize for not giving more information initially.
I can lock the sample without a problem.
I can not wobble on either the 1H or 13C side. To set up wobble on 1H I set up an experiment with just 1H, for 13C I do the same (no decoupling). I have also tried "atma xChannel". When I try to wobble on either nucleus I get "wobble signal too weak". If I try atma or atmm I also get "wobble signal too weak".
What should I try next? The receiver?
I would appreciate any suggestions.
What I have tried:
I tested the temperature of the SGU units and they were 39˚C, 42˚C, 42˚C, and 37˚C. The DDS were all 55˚C.
I appreciate Cedric Malveau telling me how to do this:
close topspin, then type ./topspin -e UniTool in the terminal,
Type ? when asked for the device name and it will list the different modules you can access and the corresponding addresses.
For me, the SGU boards were 37-412.
After typing in 37 a menu comes up, choose A (SGU Diagnostic Functions) and then choose 5 (Board temperature) or 6 (DDS Quadrature temperature).
I also switched probes and got the same results on both probes (lock works, wobble either channel:"wobble signal too weak")
I also did the diagnostics on the boards.
I tried to make sure that all connectors were snug.
Thank you very much.
