Gain Commands
5.14.1.
Set Digital Gain
Description
Sets the digital gain value applied when AGC is off
(AGC:ENABLE OFF). Digital gain can be used to ensure that the
image data fills the digital output range when offset and gain
corrections are applied. In addition, digital gain can be used to
stretch low signal images across a greater portion of the output
range. Digital gain does not inherently improve signal to noise ratio,
except by causing uniform saturation.
This command accepts multiple formats:
Integer input: 1 - 511 (no decimal)
Floating Point: 0.03125 to 16.0 (decimal used) in 1/32 steps
