Details
Data for voltage measurements, current 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 current sweep with voltage measured at every step (point):
1. Sets
the
smu
to output
starti
amperes, allows the source to settle for
stime
seconds, and then
performs a voltage 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
stopi
amperes step.
The linear step size is automatically calculated as follows:
step = (stopi – starti) / (points – 1)

Example
SweepILinMeasureV(smua, -1E-3, 1E-3, 0, 100)
This function performs a 100-point linear current
sweep starting at -1 mA and stopping at +1 mA.
Voltage is measured at every step (point) in the
sweep. Because
stime
is set for 0 s, voltage
will be measured as fast as possible after each
current step.

None
SweepIListMeasureV()
(on page 5-22) function performs a current list sweep with voltage measured at every
step (point).
