instrument channel (for example, smua refers to SMU
channel A)
startv
Sweep start voltage in volts
stopv
Sweep stop voltage in volts
stime
Settling time in seconds; occurs after stepping the source and before performing a
measurement
points
Number of sweep points (must be

2)
Details
Data for current measurements, voltage source values, and timestamps are stored in
smuX.nvbuffer1.
If all parameters are omitted when this function is called, this function is executed with the parameters
set to the default values.
Performs a linear voltage sweep with current measured at every step (point):
1. Sets the smu to output startv amperes, allows the source to settle for stime seconds, and then
performs a current measurement.
2. Sets the smu to output the next amperes step, allows the source to settle for stime seconds, and then
performs a voltage measurement.
3. Repeats the above sequence until the voltage is measured on the stopv amperes step.
The linear step size is automatically calculated as follows:
step = (stopv – startv) / (points – 1)

Example
SweepVLinMeasureI(smua, -1, 1, 1E-3, 1000)
This function performs a 1000-point linear
voltage sweep starting at -1 V and stopping at
+1 V. Current is measured at every step (point)
in the sweep after a 1 ms source settling period.
