For 12 bit output resolution:
BL = BREF * DGAIN
For 10 bit output resolution:
BL = (BREF / 4) * DGAIN
For 8 bit output resolution:
BL = (BREF / 16) * DGAIN
Where BREF is the black level set point set with the BL command and DGAIN the digital gain set with the GA
command.
The typical default values are 20. This value is based on the maximum expected noise floor and taking 5 times the
one sigma value of this noise giving 20 gray levels in 12 bit of full dynamic range of the used A/D converters.
The current set black level set points can be read back from the camera.
Command syntax: BL?
For the Adimec-1000m/S only the left black level set point applies (x).
4.2.10 Analog gain correction
(only applicable for the Adimec-1000m/D)
Due to production processes of the CCD sensor, the two outputs of the CCD sensor may not necessarily have the
exact same gain. Adimec utilizes a real time automatic correction to match the left and right channel at room
temperature. This feature is called Adimec Proprietary Matching and is implemented as standard in all Adimec-1000
cameras.
Command syntax: AGx
x = analog gain correction value ranging from –2047 .. +2047.
The correction factor is the required gain difference between the two outputs and is defined as follows:
Left gain
= ( x / 2047 ) * 7.5 %
