14: TSP command reference 2470 High Voltage SourceMeter Instrument
14-224 2470-901-01 Rev. A / May 2019
trigger.model.load() — SimpleLoop
This function loads a predefined trigger model configuration that makes a specific number of measurements.
Type TSP-Link accessible
Affected by Where saved Default value
Usage
trigger.model.load("SimpleLoop", count)
trigger.model.load("SimpleLoop", count, delay)
trigger.model.load("SimpleLoop", count, delay, bufferName)
The number of measurements the instrument will make
The delay time before each measurement (167 ns to 10 ks); default is
for no delay
Indicates the reading buffer to use; the default buffers (defbuffer1 or
defbuffer2) or the name of a user-defined buffer; if no buffer is specified,
is used
Details
This command sets up a loop that sets a delay, makes a measurement, and then repeats the loop the
number of times you define in the count parameter.
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
--set up measure function
smu.measure.func = smu.FUNC_DC_CURRENT
smu.terminals = smu.TERMINALS_REAR
smu.measure.autorange = smu.ON
smu.measure.nplc = 1
--set up source function
smu.source.func = smu.FUNC_DC_VOLTAGE
smu.source.ilimit.level = 0.1
smu.source.level = 20
smu.source.delay = 0.1
smu.source.highc = smu.OFF
--turn on output and initiate readings
smu.source.output = smu.ON
trigger.model.load("SimpleLoop", 200)
trigger.model.initiate()
waitcomplete()
--Parse index and data into three columns
print("Rdg #", "Time (s)", "Current (A)")
for i = 1, defbuffer1.n do
print(i, defbuffer1.relativetimestamps[i], defbuffer1[i])
