13-12 Factory Scripts Series 2600 System SourceMeters Reference Manual
2600S-901-01 Rev. A / May 2006 Return to Section 13 topics
TSP Project Name: KIFactoryGeneral
TSP Test Script Name: KIGeneral
Firmware Version: 1.0.2 and later
Function:
SweepVListMeasureI(smu, vlist, stime, points)
Description: Performs a voltage list sweep with current measured at every step (point):
• Sets the smu to output the first vlist volts value, allows the source to
settle for
stime seconds and then performs a current measurement.
• Sets the smu to output the next vlist volts value, allows the source to
settle for
stime seconds and then performs a current measurement.
• Repeats the above sequence until the current is measured for the last
volts value. The last point in the list to be measured is
points.
Parameters:
smu, vlist, stime, points
smu: SourceMeter Channel (A or B). Defaults to smua if all parameters
are omitted when function is called.
vlist: Arbitrary list of voltage source values:
vlist = {value1, value2, ....valueN}
stime: Settling time in seconds. Occurs after sourcing a value and before
performing a measurement.
points: Number of sweep measure points (must be ≥2).
Data: Current measurements, voltage source values and timestamps are stored in
smuX.nvbuffer1.
Example:
myvlist = {-0.1, 0.1, -1, 1, -6, 6, -40, 40, 0, 0}
SweepVListMeasureI(smua, myvlist, 500E-6, 10)
This function performs a 10-point voltage list sweep starting at the first point
in
myvlist. Current is measured at every step (point) in the sweep. The
source will be allowed to settle on each value for 500µs before a
measurement is performed.
