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. |
