PSEC3 – testing update Eric oberla Herve grabas

2 DC readout Pedestal Readout @ 10 GS/s
Same readout with ped calibration 

3 A look at linearity: Looks to be fairly linear over expected region (~150mV-1V)

4 A look at noise: -Ped readout for each channel, Mean and RMS presented
- 1 ADC count~=0.5 mV, so noise ~1-2.5mV

5 A look at bandwidth: 3dB BW 270 MHz Trying to understand limitation
(quick calc from parasitic extraction gives input BW of chip ~1GHz) Some sampled sin waves 10GS/s)
