[Dsg-hallb_magnets] qdi thresh

[Amrit Yegneswaran]

brian, 
thanks for the answers. 
you're right, the 120KHz glenn determined is not from any equipment. 
but with regards to the threshold, do you mean the QD performs a Common Mode Rejection kind of procedure. 
hope to hear from pablo.

The QD threshold uses the difference between lower and upper, so that would (or should) have been cancelled out by the lower.
