I've noticed recently that our EPR spectrometer (Bruker EMX500) has a negative offset on the baseline and it becomes very large at high receiver gain settings (goes off scale).
Is there a way to tweak the spectrometer or software settings to fix this issue?

The Bruker EMX software corrects the baseline afyet each scan... I can think of two reasons for the offset:
1) There is a very broad line there (dirty cavity?). To check it try to run your spectrum with larger sweep range (3000-4000 G) 2) Check the phase of the MW bridge
