IVER

Image VERsion

Classification:

System parameter setting / Sequence parameter setting

Command Syntax:

IVER <mode>

Limits:

<mode>

 

0 = Normal

 

1 = Invert or display alternate version

Query Syntax:

IVER?

Query Response:

<mode>

Description:

The IVER command is context sensitive. When editing a sequence

 

(while between a set of SEQB and SEQE commands), the IVER

 

command determines which version of an image is used for the

 

step being worked on. The IVER? query returns the version

 

currently assigned to the step.

 

Outside of the sequence editor, the IVER command selects which

 

version of the current image is drawn when either an ALLU or

 

IMGU command is executed. The IVER? query returns the current

 

setting of IVER.

Other Required Cmds:

The IMGU command redraws an image using the new setting.

 

The ALLU command updates hardware and redraws the test

 

image with the new setting.

Example:

I M G L T e x t _ 9 / / S e l e c t i m a g e w i t h w h i t e

 

/ / t e x t o n b l a c k

 

I V E R 1 / / S e l e c t i n v e r t e d w i t h b l a c k o n

JRAT

Justify pixel clock RATe

Classification:

Format editor control

Command Syntax: JRAT <pixel rate>

Limits:

<pixel rate> = Floating point number equal to the desired

 

pixel in MHz

Query Syntax:

None

Description:

The JRAT command scales the horizontal timing parameters of

 

the format currently in the edit buffer. The parameters are scaled

 

to produce the given pixel rate while keeping the horizontal

 

scan rate as close as possible to its original value. The following

 

parameters are scaled: Horizontal total pixels, Horizontal active

 

pixels, Horizontal sync delay in pixels and Horizontal sync pulse

 

width in pixels. The parameters are scaled so that their periods,

 

in microseconds, are as close as possible to their original values.

Other Required Cmds:

The ALLU command updates hardware to the new settings and

 

redraws the test image.

Example:

J R A T 2 8 . 3 2 2 / / A d j u s t t i m i n g t o a

 

/ / 2 8 . 3 2 2 M H z c l o c k
