 User’s Manual Triggering 11-7
NOTE When using SourceMeter autoranging, it is recommended that you use 
measure output triggers to avoid erroneous results.
Arm Layer Output Trigger — The SourceMeter can also be programmed to output 
a trigger when operation enters the Trigger Layer, or after operation leaves the 
Trigger Layer and enters back into the Arm Layer. This output trigger is typically 
sent to another instrument to signal the end of a scan or sweep.
Bench defaults
The bench defaults are listed as follows. They are also denoted in Figure 11-1 by 
the “✛” symbol.
• Arm-In Event = Immediate
• Trigger-In Source = Immediate
• Arm Count = 1
• Trigger Count = 1
• Trigger Delay = 0.0 sec
• Delay Action = 0.001 sec
• Source Trigger In Event = On
• Delay Trigger In Event = Off
• Measure Trigger In Event = Off
• Trigger Out Events = All Trigger Out Events are disabled (off) 
• Arm Out Event = Off
• Event Detection Bypasses = Never (both layers)
When the output is turned ON, the SourceMeter will run in a continuous loop 
around the trigger model. After each Measure Action, operation will continue at 
the top of the trigger model. The SourceMeter can be returned to idle by turning 
the output OFF.
