Trigger subsystemIEEE-488 ReferenceQuerycommands:AUTO?Short-form format:Response message:Query auto-count:trig:coun:auto?1 (on) or 0 (off)DescriptionWith auto-count enabled, the channel count is automatically set to the scan-list-length. For example,if there are currently 36 channels in the scan list, then enabling auto-count will set thechannel count to 36. While auto-count is enabled, changing the scan list count will change thetrigger count.If the scan list is empty, enabling auto-count will set the channel count to 1.This command is coupled to :TRIGger:COUNt which is used to manually set the channel count.When :TRIGger:COUNt is used to set the channel count, auto-count will automatically disable.Programmingexample10 OUTPUT 707; “:scan (@ 1!1:1!10)20 OUTPUT 707; “:trig:coun:auto on; auto?; :trig:coun?”30 ENTER 707; A$40 PRINT A$50 ENDLine 10 Defines a scan list (channels 1-10 of Slot 1).Line 20 Enables auto-count, queries the state of auto-count and then queries the channelcount.Line 30 Addresses the 7002 to talk.Line 40 Displays the state of auto-count and the channel count (1; 10).5.18.5:DELay :ARM[:SEQuence[1]]:LAYer2:DELay :TRIGger[:SEQuence[1]]:DELay Set Arm Layer 2 delaySet Trigger Layer delayParameters = 0 to 99999.999 Specify delay in seconds= DEFault 0 second delay= MINimum 0 second delay= MAXimum 99999.999 second delayShort-formformats:arm:lay2:del :trig:del DefaultsPower-up*RST:SYSTem:PRESetSaved power-on setup0 sec0 sec5-137
