Readout of rod with Lt software.  Modules biased to 100V.
noise plots (note that module ordering might not be the same as above):

comparison of APV frames for two different gains shows that Lt is able to set the AOH gains:
ltopto.jpg   gain = 1 (min gain=0, max gain=3)
ltopto3.jpg gain =3

Comparison of module noise profiles before and after asssembly onto rod (taken in peakinvoff mode*).  Modules biased to 250V.

A look at the evolution of the noise on module 1036 (adj. to CCU):
first run, taken with xrod (biased to 100V): mod3.jpg
taken with lt (biased to 100V) (no noise here): mod3b.jpg
another time (significant noise) (bias 250V): mod1036lt.jpg
latest (really high noise) (bias 250V): mod1036highnoise.jpg
 
 

Investigation of noise on module 1024, which seems to have high common mode noise:
noisy.jpg  taken with high-voltage cable connected (but voltage off)
noisy2.jpg  taken with high-voltage cables disconnected at the output of the CAEN
noisy3.jpg  taken with high-voltage cables connected, but the CAEN main cable disconnected from the wall
