Finding out what is gain for each channel using the Stanford pulse generator.

Setting:

Run Number: r634 && r635

Original pulse from stanford pulse generator goes to the ADC: r636 && r637

I used the attenuator for both channels and it was set to the same value: 12dB = 10.7918.

[math]X db = 20 log_{10}\frac{I_1}{I_2}[/math]

[math]\frac{I_1}{I_2} = 10^{12/20} = 3.98[/math]

Gain Calculation

Gain_for_Channel_1 = Gain_TrigOut = [math]\frac{175 \times 10.7918}{110} = 17.1688[/math]
Gain_for_Channel_5 = Gain_Strip = [math]\frac{650 \times 10.7918}{145} = 48.377[/math]
