Gain CSR

Note: The gain can be set by writing a floating point value to the Absolute Gain field or by writing
an integer value to the Raw Gain field. Refer to Section
between these two fields.
Register Base Address: 0x0E00
Field Name: Register Status
Description: The integer value in this field indicates the status of this control register:
Field Name: Absolute Gain
Description: Writing a floating point value to this field sets the global gain in dB. For example, if the value
Field Name: Absolute Min
Description: Minimum allowed floating point value for the absolute gain setting.
Field Name: Absolute Max
Description: Maximum allowed floating point value for the absolute gain setting.
Field Name: Raw Gain
Description: Writing an integer value to this field sets the global gain.
4-18
0x00 = The register is not available
0x01 = The register is available. All related settings are OK
0x80 = A value in the register is set out of range
in this field is set to +10.55, the gain would be +10.55 dB.
The gain can normally range from -3.00 dB to +20.00 dB in increments of 0.01.
The value in this field is a standard IEEE-754 single precision (32 bit) floating point number.
See Section 3.6.1 for more information about gain.
The value in this field is a standard IEEE-754 single precision (32 bit) floating point number.
The value in this field is a standard IEEE-754 single precision (32 bit) floating point number.
The value can normally range from 181 (0x00B5) to 2560 (0x0A00).
The dB of gain that the camera will apply at a given setting in this field is determined by this
formula:
dB = 20 x log ( setting / 256 )
For example, if the value in this field is set to 1200 (0x04B0), then:
dB = 20 x log (1200 / 256)
dB = 13.42
The 2 bytes in this field are interpreted as follows:
Byte 1 = Low byte of the raw value
Byte 2 = High byte of the raw value
See Section 3.6.1 for more information about gain.
