Analog Gain in the ADC
The only analog Gain available in the is located at the sensor level, in the ADC
converter.
This “Preamp Gain” is in fact a variation of the ramp of the comparator of the ADC.
Then 3 Values are available : x1, x2 and x4. A gain x1 in a 12 bits conversion is equivalent
to x4 in 10 bits.

Preamp Gain : ( GainAbs with GainSelector = AnalogAll )
Set the Pre-amplification Gain . This command is available in the CommCam “Gain & Offset” section.

Read function (ASCII): “ r pamp ”;
Returned by the camera : Integer corresponding to one of the 3 different step values :

0 : x1 (0dB)

1 : x2 (6dB)

2 : x4 (12dB)

Write function (ASCII): “ w pamp ” <int> ;

Gain: ( GainAbs with GainSelector = GainAll )
Set the Amplification Gain . This command is available in the CommCam “Gain & Offset” section :

Read function (ASCII): “ r gain ”;
Returned by the camera : Value from 0 to 6193 corresponding to a Gain range of 0dB to +8dB
calculated as following : Gain(dB) = 20.log(1+ Gain/4096).
