2. To run the i_leakage_measure() function in the KIHighC factory script, send:
-- Charges the capacitor.
smua.source.levelv = 100
smua.source.output = smua.OUTPUT_ON
delay(1)
imeas = i_leakage_measure(smua, 0, 100e-3, 300e-3, 10e-6, 100e-3)
-- The parameters in the i_leakage_measure() function represent
-- the following:
-- smu = smua
-- levelv = 0 V
-- limiti = 100 mA
-- sourcedelay = 300 ms
-- measurei = 10 uA range
-- measuredelay = 100 ms
Adjust the voltage level and source delays based on the value and type of capacitor along with the
magnitude of the voltage step and the current measure range.
