Script example
Use the smua.source.highc attribute to set and control the options for high-capacitance mode.
The programming examples and figure below illustrate how to enable high-capacitance mode.
1. To enable high-capacitance mode, send:
-- Enables high-capacitance mode.
smua.source.highc = smua.ENABLE
2. To run the i_leakage_measure() function in the KIHighC factory script, send:
-- Charges the capacitor.
smua.source.levelv = 5
smua.source.output = smua.OUTPUT_ON
delay(1)
imeas = i_leakage_measure(smua, 0, 1, 300e-3, 10e-6, 100e-3)
-- The parameters in the i_leakage_measure() function represent
-- the following:
-- smu = smua
-- levelv = 0 V
-- limiti = 1 A
-- 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.
