EQUA

EQUalization interval After vertical sync

 

pulse

Classification:

Format parameter setting

Command Syntax:

EQUA <lines>

Limits:

<lines>

 

min = 0

 

max = number of lines after vertical sync before video

Query Syntax:

EQUA?

Query Response:

<lines>

Description:

The EQUA command establishes the width of the equalization

 

interval after the vertical sync pulse in each field whenever a

 

serrated & equalized sync type is selected via either ASCT or

 

DSCT commands and selected via the SSST command. If the

 

type specified for the selected sync signal is one of the CCIR

 

types, then the actual equalization interval output by the

 

generator will be 0.5 lines shorter than the whole number

 

specified. The EQUA? query returns the current setting of EQUA.

Other Required Cmds: 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.
