Hi Mike,
Thank you for these suggestions. The error initially started to appear only
with 13C dept experiments and wasn't that much frequent. Then with the passage
of time, went frequent, and started with other experiments also, like 1H,
water suppression, and COSY. I have attached the screenshots of the error
that exactly appears. Closing the error dialog box and repeating "zg" on
the same file sometimes work making sure no problem is with the routing.
The 13C broadband experiments with pulse program zgpg30 or zgpg works smoothly
and I never have this problem with broadband experiments.
Bruker personnel remotely checked our system for this. While he was connected,
we tried with a different RF cable first and then doubled the length by joining
two cables together with a connector but it didn't help too. The actual P1 and
PLW1 in our system are 10us and 12.7W and then when we changed P1 and PLW1 to
12.5us and 8W then the zgpr water suppression experiment worked fine on the
standard sucrose sample and if we kept the power level to 0 then the error
didn't persist. Does this test confirm that the preamp isn't a culprit? what
information can be extracted from this test?
Thank you
Adil
