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.
