MiniPrototype CAEN V792 Calibration

I injected a signal into the Drift chamber preamps and read it out using the CAEN V792 ADC.

7 mV Signal

Here is a scope picture of the signal coming out of the preamp and going into the ADC (Blue) as well as the integration gate used. The signal is about 7 mv as shown below. There is a 2 mv peak to peak noise level which has structure.

The data was then collected using coda and recorded as run #189. A histogram of channel #1 is shown below.

20 mV signal

Reducing the attenuation, a 20 mV signal was sent into the ADC.

The data was then collected using coda and recorded as run #190. A histogram of channel #1 is shown below.
