) 

Set the Pre-amplification Gain. This command is available in the CommCam “Gain & Offset” section.  

 

Read function : “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 : “w pamp” <int> ;  

 

  

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.
