ASSC Analog Sync Swing Calibration factor
Classification: System parameter setting
Command Syntax: ASSC <red factor>, <green factor>, <blue factor>
or
ASSC <common factor>
Limits: <factor> (floating point accepted)
min = 0.000
max = 1.000
Query Syntax: ASSC?
Query Response: <red factor>, <green factor>, <blue factor>
Description: The ASSC command 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. Re-initializing the generator’s memory
restores the setting to factory default values of 1.000.
Other Required Cmds: None
Example: ASSC .995 .998 1.00 // Reduce red and
// green sync levels
FMTU // Update hardware to current
// buffer contents
