buffer
Reading buffer where pulsed measurements will be stored; if this is
nil
when the function is
called, no measurements will be made when the pulse train is initiated
tag
Numeric identifier to be assigned to the defined pulse train
sync_in
Defines a digital I/O trigger input line; if programmed, the pulse train waits for a trigger input
before executing each pulse
sync_out
Defines a digital I/O trigger output line; if programmed, the pulse train generates a trigger
output immediately before the start of
ton
sync_in_timeout
Specifies the length of time (in seconds) to wait for input trigger; default value is 10 s
sync_in_abort
Specifies whether or not to abort the pulse if an input trigger is not received; if pulse aborts
because of a missed trigger, a timer timeout message is returned;
true
or
false
Details
Data for pulsed voltage measurements are stored in the reading buffer specified by the
buffer
input parameter.
This function configures a current pulse train with a voltage measurement at each point. Measurements are
made at the end of the
ton
time.
This function does not cause the specified
smu
to output a pulse train. It simply checks to see if all the pulse
dimensions can be achieved, and if they are, assigns the indicated
tag
or index to the pulse train.

Example
ConfigPulseIMeasureV(smua, 0, 10e-3,
100, 0.01, 0.1, 1, smua.nvbuffer1, 1)
Set up a pulse train that uses System SourceMeter
®
instrument channel A. The pulse amplitude will be 10
mA and will return to 0 A after 10 ms. The pulse will
remain at 0 A for 100 ms and the voltage limit will be
100 V during the pulse. The pulse train will consist of
only 1 pulse, and this pulse will be assigned a
tag
index of 1.
