
Preamp Gain : ( Gain with GainSelector = AnalogAll )
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> ;

Gain: ( Gain with GainSelector = GainAll )
Set the Amplification Gain . This command is available in the CommCam “Gain & Offset” section :

Read function : “ 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).

Write function : “ w gain ” <int> ;

Tap Gain ( Gain with GainSelector = Tap X) :

Read function : “r fga <tap>”; <tap> is 1 or 2
Returns the Gain value for the tap. Ex : “ r fga1 ” returns Gain value Tap1.

Write function : “w fga <tap> <value>”

<tap> : 1 or 2

<value> : from -128 to +127 by step of 1 (0,0021dB each step)

Digital Gain ( Gain with GainSelector = DigitalAll ) : Set the global Digital Gain . This command is available in
the CommCam “Gain & Offset” section :

Read function : “ r gdig ”;
Returned by the camera : Integer value from 0 to 255. The corresponding Gain is calculated as
20log(1+val/64) in dB

Write function : “ w gdig ” <int> ;

Digital Offset ( BlackLevelRaw with BlackLevelSelector = All ) : Set the global Digital Offset . This command is
available in the CommCam “Gain & Offset” section :

Read function : “ r offs ”;
Returned by the camera : Value from –4096 to +4095 in LSB

Write function : “ w offs ” <int> ;
The Contrast Expansion (both Digital Gain & Offset) will be automatically disabled if the LUT
is enabled.

Tap Balance Gains Enable Switch ( TapBalanceGainEnable ) :

Read function : “r fgae ”;
Returns the Gain value for the tap. Ex : “ r fga1 ” returns Gain value Tap1.

Write function : “w fgae <val>” with <val> : 0 or 1

0 : Disables the Tap Balance Gains

1 : Enables the Tap Balance Gains
