Details
This function will only initiate configured pulse trains assigned to a valid tag. Configure the pulse before initiating
it using one of the ConfigurePulse* functions (refer to the Also see section).
Example
smua.reset()
smua.source.rangev = 5
smua.source.rangei = 1
smua.source.levelv = 0
smua.measure.rangev = 5
smua.measure.rangei = 1
smua.measure.nplc = 0.01
smua.measure.autozero = smua.AUTOZERO_ONCE
smua.nvbuffer1.clear()
smua.nvbuffer1.appendmode = 1
smua.source.output = smua.OUTPUT_ON
f1, msg1 = ConfigPulseVMeasureI(smua, 0, 5,
1, 0.002, 0.2, 10, smua.nvbuffer1, 1)
if f1 == true then
f2, msg2 = InitiatePulseTest(1)
print("Initiate message:", msg2)
else
print("Config errors:", msg1)
end

false when errors were encountered
A string message; if the f flag is false, msg will contain an error message; if it is
true, msg will contain a string indicating successful configuration

Configure System SourceMeter
instrument channel A to generate
a pulse train. If no errors are
encountered, initiate the pulse
train. Channel A will pulse voltage
from a bias level of 0 V to a pulse
level of 5 V. The pulse level will be
present for 2 ms and the bias level
for 200 ms, with a 1 A limit setting.
A total of 10 pulses will be
generated, and the measurement
data will be stored in
smua.nvbuffer1. This pulse
train will be assigned to tag = 1.
