Example ViSession vi;

ViStatus ret;

ViInt32 sch = 1; /* SMU1 for sweep channel */

ViInt32 mch = 2; /* SMU2 for measurement channel */

ViInt32 sm = 1; /* sweep mode: voltage-single-linear */

ViInt32 om = 2; /* output mode: voltage */

ViReal64 or = 0; /* output range: auto */

ViReal64 v1 = 0; /* start voltage */

ViReal64 v2 = 1.5; /* stop voltage */

ViInt32 pts = 11; /* point */

ViReal64 th = 0.01; /* hold time */

ViReal64 td = 0.001; /* delay time and step delay time */

ViReal64 icomp = 0.1; /* current compliance */

ViReal64 pcomp = 0.2; /* power compliance */

ViInt32 mm = 1; /* measurement mode: current */

ViReal64 mr = 0; /* measurement range: auto */

ViInt32 mpts; /* number of measurement steps */

ViReal64 sc[11]; /* source data */

ViReal64 md[11]; /* measurement data */

ViInt32 st[11]; /* status */

ViInt32 tm[11]; /* time stamp data */

ret = agb1500_setSwitch(vi, sch, 1);

ret = agb1500_setSwitch(vi, mch, 1);

ret = agb1500_resetTimestamp(vi);

ret = agb1500_force(vi, mch, om, or, v1, icomp, 0);

ret = agb1500_setIv(vi, sch, sm, or, v1, v2, pts, th, td, td,

icomp, pcomp);

ret = agb1500_sweepIv(vi, mch, mm, mr, &mpts, &sc[0], &md[0],

&st[0], &tm[0]);

For the above example, the array variables sc[], md[], st[], and tm[] will contain the

following data.

sc[n]: Sweep source setup data (voltage).

md[n]: Measurement data (current).

st[n]: Status for the md[n] data.

tm[n]: Time stamp data (measurement start time) for the md[n] data.

where, n = 0 to 10 (integer).
