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: IMGL Text_9 // Select image with white
// text on black
IVER 1 // Select inverted with black on
// white
IMGU // Draw the image as selected
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: JRAT 28.322 // Adjust timing to a
// 28.322 MHz clock
FMTU // Update hardware to current
// buffer contents
