keyword=Scope Signals DVCSTLAB3To debug the retiming circuit for BigBite I added a few channels to
the DVCSTLAB3 scope:
yellow: NIM-bar of L1A
cyan: BB retimed L1A
magenta: delayed T6 (retiming signal)
green: left arm T3
I was unfortunately not able to connect the delayed L1A for the time-out circuit in case the retiming signal is not present, i.e, no T6 present.
Figure 1 shows an example plot from the cosmics setup. There will
only be a T3 when an EDTM pulse comes through, but T6 is a much higher
rate trigger.
