8: Triggering 2470 High Voltage SourceMeter Instrument
8-46 2470-901-01 Rev. A / May 2019
Predefined trigger models
The 2470 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
l
ist 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
am
ount 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
ev
ent 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.
Preparations for using a predefined trigger model
Before starting the trigger model, you need to set up your instrument for testing, including the source
and measure settings and source and measure configuration lists.
When you load a predefined trigger model, the instrument overwrites any existing trigger models.
If you select Templates and only the Empty trigger model appears, select Empty to see the full list
of template options.
