trigger.model.load() — Simple Loop
This function loads a predefined trigger model configuration.
Type TSP-Link accessible
Affected by Where saved Default value
Function
Yes
Usage
trigger.model.load("SimpleLoop", count)
trigger.model.load("SimpleLoop", count, delay)
trigger.model.load("SimpleLoop", count, delay, readingBuffer)
count
The number of measurements to make
delay
The time before the measurement in seconds; default is 0
readingBuffer
The reading buffer; the default buffers (
defbuffer1
or
defbuffer2
) or
the name of a user-defined buffer; if no buffer is specified, this parameter
defaults to
defbuffer1
Details
This command sets up a loop that sets a delay, makes a measurement, and then repeats the loop the number of
times you defined in the count parameter.
Example
reset()
--set up measure function
smu.measure.func = smu.FUNC_DC_CURRENT
smu.measure.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])
end
--Discharge the capacitor to 0 V and turn off the output
smu.source.level=0
delay(2)
smu.source.output=smu.OFF
