GAMmA correction factor
Format parameter setting
GAMA <factor>
<factor> (floating point accepted)
min = 0.1
max = 10.0
GAMA?
<factor>
The GAMA command establishes the current analog video gamma
correction factor. The GAMA? query returns the current setting
of the gamma correction factor.
Note – See the section of the manual dealing with editing a
format with the Windows user interface for more information
on gamma correction.
Gamma correction must be enabled with the GAMC command
in order to use the gamma correction factor The FMTU command
instructs the generator to use the new setting. The ALLU
command updates hardware to the new setting and redraws
the test image.

GAMma Correction mode
Format parameter setting
GAMC <mode>
<mode>
0 = disable (don't correct)
1 = enable (correct)
GAMC?
<mode>
The GAMC command enables or disables application of the analog
video gamma correction factor. The GAMC? query can be used
to determine if the gamma correction factor is currently being
applied.
The value used for gamma correction is set with the GAMA
command. The FMTU command instructs the generator to use
the new setting. The ALLU command updates hardware to the
new setting and redraws the test image.
