Leakage Current Measurement

Table 4-13 explains an example subprogram that performs the quasi pulsed spot
measurement and displays the measurement result data (MOSFET drain current).
Leakage Current Measurement Example
void perform_meas (ViSession vi, ViStatus ret)
{
ViInt32 drain =
ViInt32 gate =
ViInt32 source =
ViInt32 bulk =
ViReal64 vd =
ViReal64 vg =
ViReal64 idcomp =
ViReal64 igcomp =
ViReal64 start =
ViReal64 hold =
ViReal64 delay =
ViReal64 meas;
ViInt32 status;
ret = agb1500_setSwitch(vi, drain, 1);
ret = agb1500_setSwitch(vi, gate, 1);
ret = agb1500_setSwitch(vi, source, 1);
ret = agb1500_setSwitch(vi, bulk, 1);
check_err (vi, ret);
ret = agb1500_force(vi, bulk, agb1500_VF_MODE, 0, 0, 0.1, 0);
ret = agb1500_force(vi, source, agb1500_VF_MODE, 0, 0, 0.1, 0);
ret = agb1500_force(vi, gate, agb1500_VF_MODE, 0, vg, igcomp,
0);
check_err (vi, ret);
Line
1 Beginning of the perform_meas subprogram.
4 to 16 Declares variables, and defines the value.
18 to 21 Enables measurement channels.
24 to 26 Applies voltage to device.
22 and 27 Calls the check_err subprogram (shown in Table 4-1) to check if
an error status is returned for the previous line.
