Analog Video Swing Calibration factor
System parameter setting
AVSC <red factor>, <green factor>, <blue factor>
or
AVSC <common factor>
<factor> (floating point accepted)
min = 0.000
max = 1.000
AVSC?
<red factor>, <green factor>, <blue factor>
The AVSC command sets the analog video calibration (or scaling)
factor that's used to adjust the level set by AVSS. Issuing the
command with a single factor sets all three analog video channels
to the same value. Issuing the command with three factors sets
each of the analog video channels to each of the given values.
The actual peak-to-peak swing of the analog video signals at
the output connectors equals the product of AVSS multiplied
by AVSC. The AVSC? query returns the current setting of AVSC
for each channel. The default factory settings are 1.000 for AVSC.
Note – The AVSC parameter is a system level parameter that
affects the analog video swing of all Formats that are recalled.
The AVSC value is retained when the generator is powered
down and back up again. Query the current setting of AVSC if
you are experiencing low or missing analog video levels.
The FMTU command instructs the generator to use the new
setting on the current format.
