Subject: PMC: ADC Channels 
The attached PNG shows the PMC error and controls signals with no calibration.

There are 3 states:

DARK - RF input disabled & output blanked. This should be a measure of the ADC noise

(-10 dB) - This is with the gain slider down at 5 dB instead of the nominal 15 dB.

Looks like the Generic DAQ board whitening is good enough for these signal levels above ~1 Hz.

From the low and high gain spectra it also looks like the UGF is ~500 Hz with the gain at 15 dB.
