AVSC

Analog Video Swing Calibration factor

Classification:

System parameter setting

Command Syntax:

AVSC <red factor>, <green factor>, <blue factor>

 

or

 

AVSC <common factor>

Limits:

<factor> (floating point accepted)

 

min = 0.000

 

max = 1.000

Query Syntax:

AVSC?

Query Response:

<red factor>, <green factor>, <blue factor>

Description:

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.

 

Other Required Cmds: The FMTU command instructs the generator to use the new setting on the current format.
