LEDS LED Status
Classification: System parameter setting
Command Syntax: None
Query Syntax: LEDS?
Query Response:
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
Limits: = 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.
