conpin(SMU1, 3, 0);
conpin(SMU2, 2, 0);
conpin(GND, 1, 0);
forcev(SMU2, vcc8); /* Apply collector voltage to vcc8. */
trigig(SMU2, +5.0E-3); /* Search for a collector */
/* current of 5 mA. */
searchi(SMU1, 5.0E-5, 2.0E-4, 15, 1.0E-3, &res22); /* Generate */
/* a current ranging */
/* from 50 uA to 200 uA in */
/* 15 iterations. Return the */
/* current resulting from the */
/* last iteration as res22. */
This example uses the trigig and searchi commands together to generate and search for a specific
current level. A search is initiated to find the base current needed to produce 5 mA of collector current. The
collector-emitter voltage supplied by SMU2 is defined by the variable vcc8. The searchi command
generates the base current from SMU1. This current ranges between 50 mA and 200 mA in 15 iterations.
The trigig command continuously monitors the current through SMU1. The base current supplied by
SMU1 is stored as the result res22.
