i_leakage_threshold()
This KIHighC factory script function measures the current and compares it to a threshold. This continues until
either the measured current drops below the threshold or the timeout expires.

No
Usage
f = i_leakage_threshold(smuX, levelv, limiti, sourcedelay, measurei, measuredelay,
threshold, timeout)
f
A Boolean flag; this flag is true when the current is below the threshold, false if
threshold is not reached before timeout expires
X
Source-measure unit (SMU) channel (for example, smua applies 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); the current limit is lower at this level and because
high-capacitance mode is active, the measure range follows
measuredelay
Delay before the first measurement after measure range is changed
threshold
The specified current that establishes the test limit
timeout
Amount of time (in seconds) to wait for the current to drop to threshold after all the
delays have occurred
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, measurements are made at a rate determined by the
smuX.measure.nplc setting.
When testing the leakage current threshold:
• Charge the capacitor before calling this function. The output of the instrument is usually at a
non-zero voltage before calling this function; when measuring leakage, this function does not
charge the capacitor.
• If testing the leakage current threshold of the device, set levelv = 0.
