Measurement

(1/NPLC seconds)

Example 1

ConfigPulseVMeasureI(smua, 0, 20, 1,

0.001, 0.080, 10, smua.nvbuffer1, 2)

Set up a pulse train that uses SourceMeter

instrument channel A. The pulse amplitude will

be 20 V and will return to 0 V after 1 ms. The

pulse will remain at 0 V for 80 ms, and the

current limit will be 1 A during the pulse. The

pulse train will consist of 10 pulses, and the

pulse train will be assigned a tag index of 2.

Example 2

local timelist = { 1, 2, 3, 4, 5 }

f, msg = ConfigPulseVMeasureI(smua, 0, 1,

100e-3, 1, timelist, 5, nil, 1)

Variable off time between pulses in a pulse

train.

Configure a pulse with 1 second on time and

variable off time, no measurement

Example 3

rbi = smua.makebuffer(10)

rbv = smua.makebuffer(10)

rbi.appendmode = 1

rbv.appendmode = 1

rbs = { i = rbi, v = rbv }

f, msg = ConfigPulseVMeasureI(smua, 0, 10,

1e-3, 1e-3, 1e-3, 2, rbs, 1)

Simultaneous IV measurement during pulse.
