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:
