AVST

Analog Video Signal Type

Classification:

Format parameter setting

Command Syntax:

AVST <type>

Limits:

<type>

 

 

 

0=none

 

 

 

1=Analog Y (grayscale)

 

2=Analog RGB (color)

 

3=Analog TV Y (grayscale)

 

4=Analog TV EYC (color subcarrier)

 

5=Analog YPrPb (color difference)

 

Must be zero (0) when any digital video type is selected

 

(DVST ≠

0).

 

Query Syntax:

AVST?

 

 

Query Response:

<type>

 

 

Description:

The AVST command establishes the type of signal that appears

 

on the analog video outputs of the generator. The AVST? query

 

returns the current setting of AVST.

 

 

 

 

Note – Certain AVST types may not be supported by all

 

generators in the 801G series.

 

Other Required Cmds:

DVST must be set to zero when analog video is used. 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.
