Hi Sameer,
I'll be interested to see if anybody's got a good solution for this.
I have a couple of possible solutions but they're kind of crude. If
you want to limit the pulse power for a specific nucleus, if it's not one of
the nuclei that's included in the PICS file then you can just set it to
whatever you want in edprobe. If you did want to edit one of the nuclei
in the PICS file for that specific probe then either I or one of my colleagues
could probably generate a custom PICS file for you that would have the power
limit you wanted and you could load that file to the probe and that would be
the permanent power limit for that probe (until you decided you wanted to
change back and loaded the original file back on.)
There are probably some other more klugey ways to do this--you might be able
to change the maximum power set in the cortab file for that nucleus accordingly.
Or you could put an attenuator between the SGU and amplifier that would decrease
the maximum size of the signal that goes from the SGU to the amp and thereby limit
the maximum power you'll get out of that channel.
Anyway, I'll be interested to see if somebody's got a more elegant solution to this.
Cheers,Mike

Hi everyone,
For a Bruker AV III console and TopSpin 3.6.5, and using a PICS probe, does
anyone know a way to limit the pulse power for a specific nucleus and/or
channel?
I know some specific solutions exist (add code to the pulprog, or editedpro
be for non-PICS probes) but I’m searching for a method that would
work on a PICS probe and across all experiments.
Thanks,
Sameer
