Lorangex - Keithley 4200A-SCS Reference Manual

Section 13: LPT library function reference
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.
