AVSS

Analog Video Signal Swing

Classification:

Format parameter setting

Command Syntax:

AVSS <level>

Limits:

<level> (floating point accepted)

 

min = 0.000 volts

 

max = 1.000 volts

Query Syntax:

AVSS?

Query Response:

<level>

Description:

The AVSS command sets the maximum peak-to-peak swing for

 

all three analog video channels. The actual peak-to-peak swing

 

of the analog video signals at the output connectors equals the

 

product of AVSS multiplied by AVSC. The AVSS? query returns

 

the current setting of AVSS.

Other Required Cmds:

Analog video must be enabled with the AVST command in order

 

to output an analog video signal. The FMTU command instructs

 

the generator to use the new setting. The ALLU command updates

 

hardware to the new setting and redraws the test image.
