HSPP <polarity>

Limits: <polarity>

0 = active-low (negative going pulse)

1 = active-high (positive going pulse)

Description: The HSPP command establishes the logic sense of the digital horizontal sync outputs. Setting

polarity to 1 causes the leading edge of horizontal sync to be a low-to-high transition. Setting

polarity to 0 causes the leading edge of horizontal sync to be a high-to-low transition. The

HSPP? query returns the current polarity of HSPP.

HSPW <pixels>

Limits: <pixels> = width of pulse in pixels

Description: The HSPW command establishes the width of the horizontal sync pulse. The HSPW? query

returns the current setting of HSPW.

HTOT <pixels>

Limits: <pixels> = number of pixels per line

Description: The HTOT command establishes the total number of pixels per horizontal line. The HTOT?

query returns the current setting of HTOT.

The pixel rate is equal to the product of: HRAT multiplied by HTOT.

❖ The current version of the firmware does not allow you to directly enter a specific pixel

rate when setting up a format. If your test specifications call for a specific pixel or dot

clock rate, enter suitable values for HRAT and HTOT to give you the desired pixel rate.

*IDN?

Query Response: QuantumData,<model#>,0,<firmware version #>

Description: The *IDN? query returns an equipment identification string formatted per IEEE-488.2

standards.

IMGA <name>

Limits: <name> = a valid MS-DOS filename

(8 characters minus any extension)

Description: Image save as < Name >

IMGB

Description: The IMGB command is used to mark the beginning of a image editing session. It switches

context to that of editing a image, thereby making the image editing commands available.

IMGE

Description: The IMGE command is used to mark the end of a image editing session. It switches context

away from that of editing a image by hiding the image editing commands.

IMGK <name>

Limits: <name> = a valid MS-DOS filename

(8 characters minus any extension)

Description: Image Kill by name command. Query returns location if named image can be deleted. If

image is read-only, then query returns zero.

IMGN

Description: The IMGN command initializes the image editing register.
