ICD Electronics Drawer SW10	ICD Electronics Drawer SW11	ICD Electronics Drawer SW12
ICD Electronics Drawer SW14	ICD Electronics Drawer SW15	ICD Electronics Drawer SW16

• Combined all channels of SW10, SW11, SW12, SW14, SW15, SW16
• Obtain approximate timing for ICD in Crate 4
• Early/Nominal = 0.67 and Late/Nominal = 0.74 for Nominal ADC > 20

ICD Crate 4

• Why do we see the "bump" at zero for the ratios?
• How can Early or Late be about zero when the Nominal > 20 ADC?
• Is it Gain related?

ICD Drawer SW10

• Is it SCA related?
• Yes!

ICD Drawer SW10

ICD Drawer SW10

• Finer scale (bins of 10)
• Y-Axis: L1scaAdd + 48*L1scaUse + 100*L2sca

ICD Drawer SW10

ICD Drawer SW10

• Looked at Crate 6 ADC Spectrum
• Zero-bias Run 127290, Pedestal Subtracted, non-zero suppressed
• No electronics for SW6. Half-tile for SW7 not yet installed

ICD Electronics Drawer SE1	ICD Electronics Drawer SE2	ICD Electronics Drawer SE3 Bad SCA
ICD Electronics Drawer SE4	ICD Electronics Drawer SE5 Bad SCA	ICD Electronics Drawer SE8

• Looked at Crate 6 ADC vs SCA
• Zero-bias Run 127290, Pedestal Subtracted, non-zero suppressed

ICD Electronics Drawer SE1	ICD Electronics Drawer SE2	ICD Electronics Drawer SE3 Bad SCA
ICD Electronics Drawer SE4	ICD Electronics Drawer SE5 Bad SCA	ICD Electronics Drawer SE8

• Do you see a pattern?
• For each set of six channels, the 3rd and 6th plots have vertical stripes.
• This corresponds to Depth 6 (drawer channel 6) and 9 (drawer channel 3) for a given Tower.
• As a reminder, recall the ADC vs SCA distributions for ICD in Crate 4.
