Example
smua.source.highc = smua.ENABLE
smua.source.levelv = 500
smua.source.output = smua.OUTPUT_ON
delay(1)
pass = i_leakage_threshold(smua, 0, 20e-3,
500e-3, 10e-6, 100e-3, 1e-6, 5)
Enable high-capacitance mode.
Charge the capacitor (500 V for 1 second).
The parameters passed on to the
i_threshold_measure() function in this
example are:
smu = smua
levelv = 0 V
limiti = 20 mA
sourcedelay = 500 ms
measurei = 10 μA range
measuredelay = 100 ms
threshold = 1 μA
timeout = 5 s
The levels and delays will depend on the
value and type of capacitor used.
Sets pass = true if the current is
measured below 1 μA in less than 1 second.

InitiatePulseTest()
This KIPulse factory script function initiates the pulse configuration assigned to tag.
Type TSP-Link accessible
Affected by Where saved Default value
Function No
Usage
f, msg = InitiatePulseTest(tag)
f
A Boolean flag; this flag is true when the pulse was successfully configured,
false when errors are encountered
msg
A string message; if the f flag is false, msg contains an error message; if it is
true, msg contains a string that indicates successful configuration
tag
Numeric identifier of the pulse configuration to be initiated
