7: TSP command reference Series 2600B System SourceMeter® Instrument
7-112 2600BS-901-01 Rev. C / August 2016
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 taken at a rate determined by the
smuX.measure.nplc setting
The function returns true if threshold is reached; the function returns false if threshold is not
reached before timeout expires.
When testing the leakage current threshold:
• Charge the capacitor before calling this function (the instrument's output is usually at a non-zero voltage
prior to calling this function; when measuring leakage, this function does not charge the capacitor).
• If testing the device's leakage current threshold, set levelv = 0.
Example
smua.source.highc = smua.ENABLE
smua.source.levelv = 5
smua.source.output = smua.OUTPUT_ON
delay(1)
pass = i_leakage_threshold(smua, 0, 1,
300e-3, 10e-6, 100e-3, 1e-6, 1)
Enable high-capacitance mode.
Charge the capacitor.
The parameters passed on to the
i_threshold_measure() function in this
example are:
smu = smua
levelv = 0 V
limiti = 1 A
sourcedelay = 300 ms
measurei = 10 µA range
measuredelay = 100 ms
threshold = 1 µA
timeout = 1 s
The levels and delays will depend on the
value and type of capacitor used.
Sets pass = true if the current is
µ
