4
Raw ATWD Data
5
ATWDA (Ch0-3): Pedestal Subtracted with FE Pulser (for a SPE size input)
6
4 Pes: ringing
7
ATWD noise
8
ATWD: baseline very stable with FE pulser. With PMT still an open question
9
FADC: gain, etc 1 SPE 30 PE
10
FADC: noise
11
COMADC and COM DAC: response and noise Ext. Power Supply Noise
12
Discriminator Scans: can trigger on 1/3 SPE 1/3 SPE signal 1 SPE signal
13
Clock 1x and 2x in ATWD / MUX: launch delay, sampling rate, jitter
14
V1 Board: ATWD noise with ALL noise source ON
15
Board V1: COM ADC Noise: All other sources ON
16
Temperature Sensor: DOMMB in Fridge
