Example

double ir12;

conpin(2, GND, 0);

conpin(SMU1, 1, 0);

limiti(SMU1, 2.0E-4); /* Limit 1 mA to 200 uA. */

forcev(SMU1, 40.0); /* Apply 40.0 V. */

measi(SMU1, &ir12); /* Measure leakage; */

/* return results to ir12. */

The reverse bias leakage of a diode is measured after applying 40.0 V to the junction.

getstatus

This command returns the operating state of a specified instrument.

Usage

int getstatus(int instr_id, long parameter, double *result);

instr_id

The instrument identification code

parameter
