Analog Video Swing Calibration factor
System parameter setting
Sets the analog video calibration (or scaling) factor that is 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 value of the AVSC if you are
experiencing low or missing analog video levels.
AVSC red_factor, green_factor, blue_factor
or
AVSC common_factor
common_factor
min = 0.000 (floating point accepted)
max = 1.000 (floating point accepted)
AVSC?
red_factor, green_factor, blue_factor
The
FMTU
command instructs the generator to use the new setting on the current format.
AVSC 1.000 .995 .998 // Reduce green and blue levels
FMTU
// Apply new factors to current format
