delicate. If you start from scratch, better
read this paper: https://arxiv.org/abs/1405.4975

Thank you for your reply. I have
read the paper already. I looked through

that different SCAs might work differently.
Like the DRS4 has a channel-to-channel jitter
  
  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.

I'm trying to troubleshoot

and CH1 output. How can I eliminate
these spikes? I'm sorry I didn't
