Setting The Gain With Vertical Binning Disabled - Basler A102K User Manual

3.6.1.1 Setting the Gain with Vertical Binning Disabled

If you know the decimal number (DN) setting for the gain on your camera, the equivalent decibel
value can be calculated using one of the following equations.
When the gain setting is between 240 DN and 511 DN, the gain curve follows a (1+x)/(1-x) shape,
which is similar to a linear-in-dB shape.
When DN setting = 240 to 511
From gain setting 512 DN to gain setting 1023 DN, the curve follows a linear-in-dB shape:
When DN setting = 512 to 1023
If the Vertical Binning feature is disabled, the gain settings result in the following amplifications:

Table 3-1: Gain Settings in dB (with Vertical Binning Disabled)
In normal operation, a gain setting lower than 240 (0x00F0) should not be used. When
the gain setting is lower than 240, the sensor output signal that is mapped to the input
of the ADC will not be linear.
