7: TSP command reference Series 2600B System SourceMeter® Instrument
7-332 2600BS-901-01 Rev. B / May 2013
Example
SweepILogMeasureV(smua, 0.01, 0.1,
0.001, 5)
This function performs a five-point linear current sweep
starting at 10 mA and stopping at 100 mA. Voltage is
measured at every step (point) in the sweep. The source is
allowed to settle on each step for 1 ms before a
measurement is performed.
The following table contains log values and corresponding
source levels for the five-point logarithmic sweep:
MeasurePoint LogStepSize LogStep SourceStepLevel
1 0.25 0.0 0.01 A
4 0.25 0.75 0.056234 A

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)
