1. Measure the width of T1 input signal in 755, and it is 100ns.
2. Change the width of GC back from 40ns to 50ns as before. The diagram attached below explained why there is no problem on the right arm VETO, even if we decreased the width by 10ns width yesterday.
3. Xscaler checked and signal is there. I will make followup entry about
the new spectrum plot when beam back.
