10-24 Triggering
Remote trigger example
Table 10-2 summarizes the command sequence for basic trigger operation. These commands
set up the SourceMeter as follows:
• Arm layer source: bus
• Arm layer count: 2
• Trigger layer delay: 0.1s
• Trigger layer count: 10
• Trigger layer output events: source and sense
• Trigger layout trigger link output line: 1
After the unit is set up, :INIT is sent to take the unit out of idle. *TRG is sent to trigger the
unit, after which it cycles 10 times through the trigger layer. A second *TRG is required to trig-
ger the unit the second time, and it then completes the second cycle through the trigger layer.
NOTE You must allow sufficient time between the first and second *TRG commands, or the
second trigger will be ignored.
