trigger.model.load() — LogicTrigger
This function loads a predefined trigger model configuration that sets up a logic trigger through the digital I/O.
Type TSP-Link accessible
Affected by Where saved Default value
Function
Yes
Usage
trigger.model.load("LogicTrigger", digInLine, digOutLine, count, clear)
trigger.model.load("LogicTrigger", digInLine, digOutLine, count, clear, delay)
trigger.model.load("LogicTrigger", digInLine, digOutLine, count, clear, delay,
bufferName)
digInLine
The digital input line (1 to 6); also the event that the trigger model will wait on in
block 1
digOutLine
The digital output line (1 to 6)
count
The number of measurements the instrument will make
clear
To clear previously detected trigger events when entering the wait block:
trigger.CLEAR_ENTER
To immediately act on any previously detected triggers and not clear them (default):
trigger.CLEAR_NEVER
delay
The delay time before each measurement (167 ns to 10 ks); default is 0 for no delay
bufferName
The name of the reading buffer, which may be a default buffer (defbuffer1 or
defbuffer2) or a user-defined buffer; defaults to defbuffer1
Details
This trigger model waits for a digital input event to occur, makes a measurement, and issues a notify
event. The notify event asserts a digital output line.
After selecting a trigger model template, you can view the trigger model blocks in a graphical format
by pressing the front-panel MENU key and under Trigger, selecting Configure. You can also add or
delete blocks and change trigger model settings from this screen. You can use the
trigger.model.getblocklist() command to view the trigger model blocks in a list format.
Example
trigger.model.load("LogicTrigger", 1, 2, 10, 0.001, defbuffer1)
Set up the template to use the digital in line and wait for a pulse from digital in line 1 to trigger measurements.
Pulse digital out line 2 when the measurement is complete.
Make 10 measurements, with a delay of 1 ms before each measurement.
Store the measurements in
defbuffer1
