We have a Varian Inova NMR spectrometer (400 MHz), which has been returning intermittent ToF glitches when acquiring 29Si data. This center glitch is accompanied by 2 kHz chirps across the entire spectrum.
The trouble is that the errors occur primarily under automation conditions. When I sit down at the console to reproduce the glitch the instrument works splendidly. It's also interesting that the problem seems to be confined to 29Si acquisitions, 13C experiments don't show this same problem.
Thoughts are appreciated,
