SCPI Instrument Command List

Description	Use this command to set up a counted loop across one or more
	segments.
	If nested loops are used, the counted loop must be embedded into the
	infinite loop completely.
Example	To set up an infinite loop over segment 2 to segment 4 and a counted loop
	across segment 2 and segment 3:
	:ARM:SOUR EXT1	Set arming source to EXT-IN
	:ARM:MODE STAR	Set arming mode to started
	:ARM:SENS POS	Arm on positive level
	:DIG:PATT:LOOP:INF:STAR SEGM2	Set jump destination to segment 2
	:DIG:PATT:LOOP 100	Set number of repetitions of
		segment2 and segment 3
	:DIG:PATT:LOOP:STAR SEGM2	Set start of counted loop
	:DIG:PATT:LOOP:LENG 2	Set length of counted loop
	:DIG:PATT ON	Switch on PATTERN mode

Command	:DIG:PATT:LOOP:INF
Long	:DIGital[:STIMulus]:PATTern:LOOP:INFinite[:STATe]
Form	Set & Query
Parameter	ON OFF 1 0
*RST value	ON
Description	Use this command to set up an infinite loop from the last used segment
	to the destination segment.
	The infinite loop is ignored, if :ARM:SOURce is IMMediate
	(CONTINUOUS mode), since in continuous mode there has to be a jump
	back to the start of the pattern (always from segment 4 to segment 1).
Example	To setup an infinite loop over segment 2 to segment 4:
	:ARM:SOUR EXT1	Set arming source to EXT-IN
	:ARM:MODE STAR	Set arming mode to started
	:ARM:SENS POS	Arm on positive level
	:DIG:PATT:LOOP:INF ON	Enable infinite loop
	:DIG:PATT:LOOP:INF:STAR SEGM2	Set jump destination to segment 2
	:DIG:PATT:LOOP 1	Disable counted loop
	:DIG:PATT ON	Switch on PATTERN mode
