ASSC
Analog Sync Swing Calibration factor
Class
System calibration settings
Description
Sets the analog video calibration (or scaling) factor that's used to adjust the level set by
ASSS. 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
composite sync signals at the output connectors equals the product of ASSS multiplied by
ASSC. The ASSC? query returns the current settings of ASSC. The default factory setting
is 1.000 for this parameter.
Note: The ASSC parameter is a system level parameter that affects the analog video
swing of all formats that are recalled. The ASSC value is retained when the generator is
powered down and back up again. Query the current setting of ASSC if you are
experiencing problems with low or missing analog composite sync levels. Reinitializing the
generator's memory restores the setting to factory default values of 1.000.
