AV500 UPDATE : BF1 SHIFT COMPLETE

The Base Frequency of the spectrometer is now reset to : 499.956572 MHz. Getting the line shape close to factory spec is still a work in progress. But, the current resolution achieved is comparable to the values with which we were operating prior to the frequency shift.  Existing user created parameter sets and the Bruker library are recalibrated to the new base frequency.  If you are in the habit of using only a ‘dataset’ to spawn a new experiment,  remember to run the ‘edsp’ command and set the BF1 to the default value.  You won’t see any signal, otherwise.
