Using SCPI:

Send the following code:

*RST

SENSe:FUNCtion "VOLT"

SENSe:VOLTage:RANGe:AUTO ON

SENSe:VOLTage:UNIT OHM

SENSe:VOLTage:OCOM ON

SOURce:FUNCtion CURR

SOURce:CURRent 5e-6

SOURce:CURRent:VLIM 10

SENSe:COUNT 5

OUTPut ON

TRACe:TRIGger "defbuffer1"

TRACe:DATA? 1, 5, "defbuffer1", SOUR, READ

OUTPut OFF

The front-panel display will look similar to the following example.

Using TSP commands:

Send the following code:

reset()

smu.measure.func = smu.FUNC_DC_VOLTAGE

smu.measure.autorange = smu.ON

smu.measure.unit = smu.UNIT_OHM

smu.measure.count = 5

smu.source.func = smu.FUNC_DC_CURRENT

smu.source.level = 5e-6

smu.source.vlimit.level = 10

smu.source.output = smu.ON

smu.measure.read(defbuffer1)

for i = 1, defbuffer1.n do

print(defbuffer1.relativetimestamps[i], defbuffer1[i])

end

smu.source.output = smu.OFF
