Thefollowing parameters may be specified:– ONCE: Causes the list to advance only one point after each trigger. Triggersthat arrive during a dwell delay are ignored– AUTO: Causes the entire list to be output sequentially after the starting trigger,paced by its dwell delays. As each dwell delay elapses, the next point isimmediately outputLIST:TTLTrgThis command sets the sequence of Trigger Out list points. Each point which is setON will cause a pulse to be output at Trigger Out when that list step is reached.Those entries which are set OFF will not generate Trigger Out pulses.The order in which the list points are given determines the sequence in whichTrigger Out pulses will be output when a list is triggered. Changing list data whilea subsystem is in list mode generates an implied ABORt.Command syntax [SOURce:]LIST:STEP Parameters ONCE | AUTO*RST value AUTOExamples LIST:STEP ONCEQuery syntax [SOURce:]LIST:STEP?Returned parameters Related commands LIST:COUN LIST:DWELCommand syntax [SOURce:]LIST:TTLTrg {, }Parameters 0 | 1 | OFF | ONExamples LIST:TTLT 1, 0, 1 LIST:TTLT ON, OFF, ONQuery syntax [SOURce:]LIST:TTLTrg?Returned parameters 0 | 1 {,0 | 1}Related commands LIST:TTLT:POIN?
