3: LPTLib command reference S530/S540 KTE Linear Parametric Test Library (LPTLib) User's Manual
3-42 S530-900-01 Rev. E / September 2017
This command must be called in the test sequence before the associated forceX, sweepX, or
searchX command is used to generate the voltage or current. The limitX command also sets th
e
t
op measurement range of an autoranged measurement.
The limits set within a particular test sequence are cleared when the devint command is called.
Example
double ibceo, vbceo;
.
.
conpin(2, 3, GND, 0);
conpin(SMU1, 1, 0);
limitv(SMU1, 150.0); /* Limit voltage at 150 V. */
forcei(SMU1, ibceo); /* Force current through the DUT. */
measv(SMU1, &vbceo); /* Measure breakdown voltage; */
. /* return results to vbceo. */
.
This example measures the breakdown voltage of a device. The limit is set at 150 V. This limit is
necessary to override the default limit of the SMU, which would otherwise be in effect.

measX (on page 3-45)
rangeX (on page 3-60)
searchX (on page 3-71)
sweepX (on page 3-88)
lorangeX
This command defines the bottom autorange limit.
Usage
int lorangei(int instr_id, double range);
int lorangev(int instr_id, double range);
instr_id
The instrument identification code
range
The value of the instrument range, in volts, amperes, farads, or siemens
