KIHighC
The KIHighC factory script is made up of two functions:
i_leakage_measure()
and
i_leakage_threshold()
. These functions are intended to be used when HighC mode is
active. Output is generally at a non-zero voltage prior to calling these functions. These functions
can also be used to step the voltage to zero volts in order to measure the leakage current.

KIHighC TSP test script: i_leakage_measure()
TSP project name:
KIHighC
TSP test script name:
KIHighC
Function:
i_leakage_measure(smu, levelv, limiti, sourcedelay, measurei, measuredelay)
Description
Performs a single current measurement.
Parameters
smu, levelv, limiti, sourcedelay, measurei, measuredelay
smu:
SourceMeter instrument Channel (A or B).
levelv:
Voltage level to step to.
limiti:
Current limit setting for the voltage step.
sourcedelay:
Delay to wait before lowering the current limit
for measurement.
measurei:
Measure range for the current measurement.
Note the current limit is lower at this level and
it is presumed (because HIGHC mode is
active) the measure range will follow.
measuredelay:
Delay to wait after lowering the current limit
before taking the measurement.
Return
values
imeas:
The measured current.
Output
Data
The measured current.
Example
smua.source.levelv = 5
--charge the cap
smua.source.output = smua.OUTPUT_ON
delay(1)
imeas = i_leakage_measure(smua, 0, 1, 300e-3)
The parameters passed on to the
i_leakage_measure()
function are as
follows:
• smu = smua
• levelv = 0V
• limiti = 1A
• sourcedelay = 300ms
• measurei = 10 uA range
• measuredelay = 100 ms
The levels and delays will depend on the value and type of capacitor used.
