SCPI Instrument Command List

Description Use this command to set/read the number of trigger events (pulse periods) to be generated for each arming event in pulse and burst mode (in pattern mode the number of trigger events depends on the used sequence). This corresponds to selecting the event mode on the MODE/ TRG screen:

	PULSES	Set a trigger count of 1 so that a single pulse period is
		generated for each arming event.
	BURST of	Set a trigger count of 2 to 65504 so that a burst of 2 to 65504
		pulse periods is generated for each arming event. Switch off
		pattern mode so that a pulse is generated in each pulse
		period. (:DIG:PATT OFF)
NOTE	For a started burst this command will reduce the number of pulses on
	channel 1 and channel 2 (:TRIGger:COUNt:PULSes[12]) to the value
	set by :TRIGger:COUNt. Changes of the number of pulses on the
	channels will increase the value to of :TRIGger:COUNt to reflect the
	changes on the channels.
Examples	To set STARTED BURST of 16 pulse periods and 6 Pulses at
	Out1, the burst are started by a positive level at the EXT INPUT:
	:ARM:SOUR EXT1		Set arming from EXT INPUT
	:ARM:MODE STAR		Set started mode
	:ARM:SENS POS		Set arming on positive level
	:TRIG:COUN 16		Burst length 16
	:TRIG:COUN:PULS1 6		Number of pulses at OUTPUT 1
	:TRIG:SOUR INT1		Pulse period trigger from internal PLL.
	:DIG:PATT OFF		Disable pattern operating mode
	To set GATED PULSES Pulses at Out1, gated by a positive level at the
	EXT INPUT:
	:ARM:SOUR EXT1		Set arming from EXT INPUT
	:ARM:MODE GAT		Set arming on levels
	:ARM:SENS POS		Set arming on positive level 1 pulse period
	:TRIG:COUN 1		Single pulse output mode
	:TRIG:SOUR INT1		Pulse period trigger from internal PLL.
	:DIG:PATT OFF		Disable pattern data
