i_leakage_measure()
This KIHighC factory script function performs a current leakage measurement after stepping the output voltage.
Type TSP-Link accessible
Affected by Where saved Default value
Function No
Usage
imeas = i_leakage_measure(smu, levelv, limiti, sourcedelay, measurei, measuredelay)
imeas
The measured current
smu

instrument channel (for example, smua refers to SMU
channel A)
levelv
Voltage level to step to when this function is called
limiti
Current limit setting for the voltage step
sourcedelay
Delay to wait before lowering the current limit for measurement
measurei
Current limit (and measure range); note the current limit is lower at this level and
because high-capacitance mode is active, the measure range will follow
measuredelay
Delay to wait after lowering the current limit before taking the measurement
Details
This function causes the smu to:
• Change its current limit to limiti with a voltage output of levelv for sourcedelay time, and then
changes its current limit to measurei (that also changes the measurement range to measurei) for
measuredelay time
• When measuredelay time expires, a measurement is taken and returned as imeas.
When measuring leakage current:
• Charge the capacitor before calling this function (the instrument's output is usually at a nonzero voltage
before calling this function; when measuring leakage, this function does not charge the capacitor).
• Set levelv = 0
