Example 2
-- decimal 18 = binary 0000 0000 0001 0010
enableRegister = 18
status.system5.enable = enableRegister
Uses a decimal value to set bits B1 and
B4 of the system summary 5 enable
register.

SweepILinMeasureV()
This KISweep factory script function performs a linear current sweep with voltage measured at every step (point).

Usage
SweepILinMeasureV(
smu, starti, stopi, stime, points
)
smu
System SourceMeter
®
instrument channel (set to
smua
)
starti
Sweep start current in amperes
stopi
Sweep stop current in amperes
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 voltage measurements, current source values, and timestamps are stored in
smu
X
.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)
