trigger.model.load() — Duration Loop
This function loads a predefined trigger model configuration that makes continuous measurements for a specified
amount of time.
Type TSP-Link accessible
Affected by Where saved Default value
Function
Yes
Usage
trigger.model.load("DurationLoop", duration)
trigger.model.load("DurationLoop", duration, delay)
trigger.model.load("DurationLoop", duration, delay, bufferName)
trigger.model.load("DurationLoop", duration, delay, bufferName, readingBlock)
duration
The amount of time for which to make measurements (500 ns to 100 ks)
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
readingBlock
Define a measure or digitize block for the trigger model; options are:
• trigger.READING_ACTIVE: Add a measure or digitize block to the trigger
model based on the active function; if no option defined,
trigger.READING_ACTIVE is used
• trigger.READING_MEASURE: Adds a measure block to the trigger model
•
trigger.READING_DIGITIZE
: Adds a digitize block to the trigger model
Details
When you load this predefined trigger model, you can specify amount of time to make a
measurement and the length of the delay before the measurement.
The out line of the EXT TRIG IN/OUT rear-panel terminal is asserted at the end of each
measurement.
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
reset()
-- Set up measure function
dmm.measure.func = dmm.FUNC_DC_CURRENT
-- Initiate readings
trigger.model.load("DurationLoop", 10, 0.01)
trigger.model.initiate()
Reset the instrument.
Set the instrument to measure current.
Load the duration loop trigger model to take measurements for 10 s with a 10 ms delay before each
measurement.
Start the trigger model.
