I am setting up a new DRS4 rev5
but using drivers and software we were recently

with old software. I try to keep the current
software compatible with old boards, but

we modified drs_exam.cpp to read
all 4 channels from the DRS4 and apply directly

  684   Wed May 2 12:12:42 2018 Stefan RittPeak at 0 mV in tracesI note that your peak at zero is exactly
twice as high as the bins left and right,
so this looks to me like a binning problem

thank you for the quick reply.
All the bins in the previous histograms have

following your example, we tried
to perform the same measurement, using drs_exam

  692   Tue May 8 14:43:03 2018 Stefan RittPeak at 0 mV in tracesThe DRS chip is read out with a 12 bit
ADC, thus the phyical resolution is roughly
1V/4096 = 0.24 mV. I say roughly since the

I wonder if there is a way to pass
parameters to drscl. What I specifically

But there is a simple C program drs_exam.cpp,
which connects to a board and safes some
