SCAN

SCAN fields per frame

Classification:

Format parameter setting

Command Syntax:

SCAN <fields>

Limits:

<fields>

 

1 = progressive (non-interlaced)

 

2 = interlaced

Query Syntax:

SCAN?

Query Response:

<fields>

Description:

The SCAN command establishes the number of fields scanned

 

per frame. Set to one (1) for progressive (non-interlaced) scan

 

and two (2) for interlaced scan. The SCAN? query returns the

 

current setting of SCAN.

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.

Example: S C A N

SDLY

Sequence step DeLaY

Classification:

Sequence parameter setting

Command Syntax:

SDLY <delay>

 

Limits:

<delay> Delay time in seconds as a floating point number

 

min = 0.0 seconds

 

max = 1.70E38 seconds (infinity for all practical purposes)

Query Syntax:

SDLY?

 

 

Query Response:

<delay>

 

 

Description:

The SDLY command sets how long a sequence step will pause

 

before advancing to the next step in the Auto run mode. A

 

sequence step will use the last value set by the SDLY command.

 

The SDLY? query returns the current setting of SDLY.

Other Required Cmds:

SMOD setting must be equal to three (3) in order for the SDLY

 

setting to have any affect on sequence operation.

Example:

S D L Y 5 . 0
