is it possible to set a completely
negative input range like -1 to 0 or -0.95

As I said, people running this under Windows
or MacOS are fine, so maybe this calls for

the USB connection is unstable to the evaluation

After some times i init my board,

  606   Wed Apr 19 12:17:25 2017 Stefan RittWave rotation during transfer from the board?This is correct. Actually the amplitude
array is rotated already inside the DRS4
chip. So the readout starts with the stop

  604   Thu Apr 13 17:10:58 2017 Christian FarinaStand-alone Time Calibration for PSI BoardThank you for your help Stefan. I will
try to get the TC part isolated.

  
  603   Thu Apr 13 17:02:01 2017 Stefan RittStand-alone Time Calibration for PSI BoardThan you can try to isolate the code. Note
that different SCAs might work differently.
Like the DRS4 has a channel-to-channel jitter
  
  602   Thu Apr 13 16:54:32 2017 Christian FarinaStand-alone Time Calibration for PSI BoardHi Stefan,

Thank you for your reply. I have
read the paper already. I looked through
  
  601   Thu Apr 13 16:50:18 2017 Stefan RittStand-alone Time Calibration for PSI BoardHard to say. Timing calibration is quite
delicate. If you start from scratch, better
read this paper: https://arxiv.org/abs/1405.4975

I was trying to create a stand-alone
program that would perform a time calibration

makes an internal reset during the power

I have still the RESET issue in mind:
