fifo looks ok, we do see 10% difference between 4 and 24 sum, 24 is higher ADC side 24 should be smaller, take a run 1724 to see.
24 has -10mV offset, 4 has -2mV offset before filter. (psum) 24 has no offset, but 4 has -10mV offset (sum)
after filter? is not performed.
run 1724 pulser goes to psum 4 and psum 24, sum also
RUN 1725 switch cables between 4 and 24 on the ADC side to see difference means the problem stays with cables??
RUN 1727 pulser goes to preshower left channle 4 and 24. Try to check the software sum. individual ADC, 4 is 3000 and 24 is 4200
psum 1600 (4) 1600 (24) psum 1700 (3) 1650 (23)
sum 1650 (4) 1350 (24) sum 1750 (3) 1300 (23)
RUN 1728 pulser goes to preshower right channel 4 and 24
individual ADC, 4 is 4400 and 24 is 4200
psum 1600 (4) 1650 (24) psum 1700 (3) 1650 (23)
sum 1650 (4) 1350 (24) sum 1750 (3) 1350 (23)
RUN 1729 is after fixing the problems in the preshower left
RUN 1731 to check the shower amplifier.
