  782   Fri Oct 25 16:39:07 2019 Stefan RittComputing corrected time from binary data...what is t_0,0?t0,0 refers to the time of cell #0 of channel
#0. So basically you keep channel 0 fixed,
calculate the difference of each channel's

anyone know what the term t0,0 refers

  780   Tue Oct 15 08:14:17 2019 Danyanghow to acquire the stop position with channel cascadingThanks a lot. The problem is solved when
A3-A0 is set 1101 and srclk keeps low.

with 01010101b, then all you have to do after
a trigger is to set A3-A0 to 1101. The WSROUT
  
  778   Mon Oct 14 13:44:26 2019 Danyanghow to acquire the stop position with channel cascadingYes, firstly I configured the chip
with 4x2048 bins by setting the Write Shift
Register to 01010101b, A3-A0

Shift Register only if you do channel cascading,

you like you can terminate it with 100 Ohm
differentially and route it with 100 Ohm.
