First thing is to do another voltage calibration. Disconnect input, "Config", "Execute Voltage Calibration". If this does not fix the problem, the board is probably broken. This can happen if you send very high input singals to the board (like >10V) and exceed the maximul allowed limit from the datasheet. In that case the board needs to be repaired. Please contact me directly (via email) so that we can make you a quote.
Best regards,

Dear Stefan,
I am using an DRS4 board to record the signals from an plastic scintillator detector. It was working really good, yet a few day ago the signals became "not right". When I checked the signal using an oscilloscope it show the normal signals previously recorded. The signal amplitude are clearly reduced (from 0.3 in oscilloscope to lower than 0.1 in DRS4). Can you show me how to show this problem?
Thank you very much!
Best Regards,
Thien
