Conditions:
Top half connected
Tchiller=+15C (hybrid temp range from 14.85 to 15.46, not correlated with position on SVT cooling manifold?)
Vbias=21V
Ch.3.07 and 3.10 showed >500mA before config but ok after config sent.
Applied default FIR filter
Removed thresholds
Hybrid ID | DAQ Hybrid | Baseline data ok? | Comment |
---|---|---|---|
| F4_H0 | Y | Noise~85ADC? |
| F4_H1 | Y | Noise~70ADC |
| F4_H2 | Y | Noise ~85ADC except APV4 (edge with ch's=511,639) has x2 noise, increasing towards edge |
| F5_H0 | Y | Noise ~65ADC, few channels w/ 1/2 noise (around 180,210,220) |
| F5_H1 | N | No data from any APV? But APV's are in sync. |
| F5_H2 | Y | Noise ~80ADC |
| F6_H0 | Y | Noise ~80ADC |

Not sure the filtering is working correctly? Is the mapping between filter constants and hybrids correct?
Compare hybrid F4_H0.
