Model 2651A High Power System SourceMeter® Instrument Reference Manual Section 7: Command reference

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.

None

SweepVListMeasureI()

This KISweep factory script (on page 5-22) function performs a voltage list sweep with current measured at every

step (point).
