With a terminator at Input 1 of the LSC-REFL Servo CM board, we measured the amplitude spectrum (Vrms/sqrtHz):

• At Output 2 w/ everything turned off or zero (CM_ElecNoise_Out2_V.txt)
• At Fast output w/ everything turned off or zero (CM_ElecNoise_Fast_V.txt)
• At Fast output w/ the configuration in alog 10969 (i.e. Input 1 gain 11dB, Common Comp ON, Fast Gain 6dB, rest off/zero) (CM_ElecNoise_FastCorr_V.txt)

With a terminator at the SlowMon of the DAQ channels, I measured the ADC Noise of LSC_REFL_SERVO_SLOW_OUT (/ligo/home/alexan.staley/Public/ADC_ElectronicsNoise_03252014.xml ref 4)

We also measured the amplitude spectrum from Output 2 of the CM board with the COMM PLL locked, and input 1 of the CM board at 0dB (CommPLL_NoiseSpecV_Out2.txt).
