LEDS
LED Status
Classification:
System parameter setting
Command Syntax:
None
Query Syntax:
LEDS?
Query Response:
<decimal number from 0 to 255>
Description:
The LEDS? query returns the current status of the generator’s
signal generating hardware as a single decimal number. The
number corresponds to the status of the lighted push-button on
the generator in normal operation. The easiest way to interpret
the number is to first convert it to an eight (8) digit binary
number. A one (1) in a given position, from MSB to LSB,
corresponds to the following hardware settings:
Master output control gated ON
(MSB)
Digital Separate (HS&VS) Sync selected
Digital Composite Sync selected
Analog Composite Sync selected
Blue video enabled
Green video enabled
Red video enabled
Alternate image version selected
(LSB)
Other Required Cmds:
None

LIMI
draw video LIMIts markers
Classification:
Custom image primitive
Command Syntax:
LIMI <color>
Limits:
<color> = available colors
Query Syntax:
None
Description:
Places nine (9) markers that define the active video area. An L-
shaped marker is at each corner. T-shaped markers are centered
along each edge of video and a small cross is at the center of
video. The primitive uses a single parameter … color.
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.
