Dear all,
I have been (with the support of Bruker) trying to install a 2htx-board
on an three-channel AVI with centos5 and Topspin 2.1.
The cable seems to be correct, however he was complaining that the 2htx
is routed to the 300W amplifier. I have corrected that via the bsms and
routet it to output 4.
Now there are no complaints, I can also do a 3DShim and 1DShim on a
sucrose sample. However, as soon as I want to start topshim on any
deuterated solvent, he aborts with the error "Raw check - no signal at all".
I can measure deuterium, the lock works, so I am pretty sure, it is not
the deuterium per se which does not give a signal.
Anyone any thoughts on this? Bruker seems to be at their wits end on
this either...
Thanks and best, André
