Selecting Trigger Source

The trigger source generates a cue signal that initiates a measurement process. Four types of trigger sources are available:

1. Press Trigger Mode, then select the desired trigger source.
    

   Trigger Sources	Function
   Internal (Internal)	Uses a consecutive signal generated by the firmware as a trigger source. Triggers are sent immediately following the completion of each measurement.
   External (External)	Uses the external trigger input terminal (BNC) or handler interface as a trigger source.
   Manual (Manual)	A trigger is generated by pressing Trigger.
   Bus (Bus)	A trigger is generated through GPIB/LAN/USB.

2. When External is selected as a trigger source, click Input Polarity to select trigger polarity.
    

   Softkey Label	Function
   Negative	Detect external trigger with negative edge.
   Positive	Detect external trigger with positive edge.

• The setting for trigger polarity is NOT valid for the external trigger from the handler interface.
