Hello
Some of you may remember Bruker spectrometers before the AVANCE series. We have a DMX console that has been our bread and butter solids instrument. Unfortunately the old timer in the lab (the spectrometer not me) is no longer working correctly. While trying to tune the probe, an error indicates a problem with the 80MHz input at the TCU and the 40MHz input at the RCU. The problem actually stems from an unstable 80MHz output at the PTS. When an external 80MHz source is used, the error no longer pops up. However, the spectrometer is still unable to tune- that is the wobble curve is a 'spikey mess'.
Those of you with a better understanding... is there a way to synchronize an external 80MHz source with the spectrometer and possibly avoid buying a replacement PTS?
I'm also on the lookout for used PTS D620. :)
