    TRIGGER SUBSYSTEM The :TRIGger subsystem commands are used to control the sweep trig- gering functions of the MG369XA. The subsystem commands and pa- rameters are described below. The :TRIGger command, along with the :ABORt and :INITiate commands, comprise the Trigger Group of com- mands.
  • Page 181 Requests the currently programmed sweep trigger source. NOTES: Only one trigger source can be specified at a time, and all others will be ignored. Sending :TRIGger:SOURce IMM;INITiate:CONTinuous ON places the se- lected sweep in auto trigger mode. 3-144 MG369XA SCPI PM...
  • Page 182 NOTES: :SEQuence3 is the trigger sequence for the internal pulse generation function of the MG369XA (see the [:SOURce]:PULSe subsystem com- mands). The command :TRIGger:SEQuence3:SLOPe sp POSitive | NEGative only affects the triggering of the internal pulse generator when :TRIGger:SEQuence3:TYPE is set to GATed, TRIGgered, or TRGDelay.
  • Page 183 Only one mode of triggering can be specified at a time, and all others will be ignored. GATed and COMPosite triggering modes are available in single pulse ([:SOURce]:PULSe:COUNt sp 1) mode only. Pulse delay1 ([:SOURce]:PULSe:DELay1) is not used with FREerun, GATed, and TRIGgered modes of triggering. 3-146 MG369XA SCPI PM...
