Hi David,
I never saw this particular error, but it could mean that the power level
for p1 is too high for 30us.

Hi all,
Encountered an error I have never seen before. Amplifier on an Avance III
is giving a "Mismatch Fault General Gating Fault" error (see attached image).
History: Instrument has been running fine (mostly H1, C13, P31, Si29). I
went to run an HSQC (hsqcedetgpsisp2.3) and encountered that error shortly
after the acquisition started. Figuring I would tackle that another day, I
switched pulse sequences (hsqcdietgpsisp). That experiment at least ran to
completion, but with no correlations. Went to double check the C13 pw90.
Switched to zg pulse sequence and ran a scan at my calibration (10us).
Looked normal. Changed p1 from 10us to 30us to ensure the peak inverted and
I was at least reasonably close to 90/270. Simply changing p1 from 10us to
30us caused the gating error to show up again (this was reproducible).
Not very sure where to go from here. Any one able to provide some insight
please?
Regards,
David
