Triggering
GPIB defaults
The GPIB defaults are listed as follows. They are also denoted in Figure 10-9 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
•
Enabled event detector = Source Event Detector (Delay and Measure detection
disabled)
•
Enabled output triggers = None
•
Event detection bypasses = Acceptor (both layers)
With output turned ON (OUTPut ON), the SourceMeter will perform one SDM cycle when
the INITiate command is sent. After the measurement, the SourceMeter returns to the idle state.
Operation summary
The trigger model is designed to offer versatility for the various source-measure applica-
tions. Typically, it allows you to perform a speci
fi
ed number of measurements at various source
levels.
For example, assume you want to perform three measurements each at two different
V-source levels. (1V and 2V). To do this, set the arm count to two (arm:count 2), the trigger
count to three (trigger:count 3), and use the list sourcing mode with the following de
fi
ned list:
source:list:volt 1, 1, 1, 2, 2, 2
On the
fi
rst pass through the trigger model, three measurements will be performed at the 1V
source level. On the second pass, three measurements will be performed at the 2V source level.
After the last measurement, the SourceMeter returns to the idle state. Note that the product of
the arm count (
fi
nite value) and trigger count determines the number of measurements that are
performed. In this example, six measurements are performed (2
×
3).
