hi Xu,

   Did you guys power cycle the readout system after the mysterious noise appeared with GC26? (I assume it was power cycled in the changing to GC13. I wonder if power cycling might have fixed it or it was definitely confirmed to be the cable GC26, e.g. you put that one back again and problem appeared again even w/o bias?

   I can't recall that we ever had such a problem before. Please inspect the pins on the connectors, though I guess you already have done that and would have mentioned if one looked damaged.

   On the T board fitting - is it going to be possible to fasten the T board to mechanical structure with screws and nuts? If not, I'm a little worried that moving the cable around as things get installed may flex something and cause troubles.
