Hi,

We are using the DRS4 Evaluation Board as a digitizer in our laboratory.
We found a strange behavior in the saved files, more specifically the time difference between two consecutive points is not constant, also after the Timing Calibration.
As an example, I paste a piece of a xml file saved using the drsosc program, acquiring CH1 (open):

We found the same behavior saving events in the binary format, and then reading them with the read_binary.cpp

Is there a way to fix our issue?

Thanks a lot
