Trigger Model - Keithley 2461 Reference Manual

Model 2461 Interactive SourceMeter® Instrument Reference Manual

Trigger model

The trigger model has changed significantly from the Series 2400 to the Model 2461.
The ARM subsystem commands are no longer available. The commands for the trigger model are
now in the TRIGger subsystem.
The Model 2461 includes predefined trigger models for common applications. You can use these
predefined trigger models without changing them, or you can modify them to meet the needs of your
application.
The predefined trigger models include:
•
Empty: Clears the present trigger model.
•
ConfigList: Creates a trigger model that loads a source and measure configuration list. The lists
are iterated until every index in the configuration list with fewer indexes has been loaded. For
example, if the measure list has seven indexes and the source configuration list has 10, it will
iterate through seven indexes of the source list and all of the measure list. However, if the source
list has three indexes and the measure list has five, it will iterate through three indexes of
measure list and all of the indexes in the source list. At each index when the output is turned on,
a measurement is made and the output is turned off.
•
LogicTrigger: Creates a trigger model that waits on an input line, delays, makes a measurement,
and sends out a trigger on the output line a specified number of times.
•
SimpleLoop: Creates a trigger model that makes a specified number of readings. A count
parameter defines the number of readings.
•
DurationLoop: Creates a trigger model that makes continuous measurements for a specified
amount of time. When you start this trigger model, the output is turned on.
•
LoopUntilEvent: Creates a trigger model that makes continuous measurements until a specified
event occurs.
•
GradeBinning: Creates a trigger model that successively measures components and compares
their readings to high or low limits to grade components.
•
SortBinning: Creates a trigger model that successively measures components and compares
their readings to high or low limits to sort components.
