smuX.measure.Y
smuX.measure.iv
X = SMU channel (a or b)
Y = SMU measure function (v, i, r or p) where:
v = voltage, i = current, r = resistance, p = power
Function Performs one or more measurements.
Usage There are three ways to use this function:
reading = smuX.measure.Y()
reading = smuX.measure.Y(rbuffer)
reading = smuX.measure.iv(ibuffer, vbuffer)
reading Returns the last reading of the measurement process.
rbuffer A reading buffer object where all the reading(s) will be stored.
ibuffer A reading buffer object where current reading(s) will be stored.
vbuffer A reading buffer object where voltage reading(s) will be stored.
Remarks
• This function returns only the last actual measurement as reading. To use the
additional information acquired while making a measurement, a reading buffer must
be used. If the instrument is configured to return multiple readings when a
measurement is requested, all readings will be available in
rbuffer if one is
provided, but only the last measurement will be returned as
reading.
• The smuX.measure.iv function stores both current and voltage readings in
respective buffers (current and then voltage are stored in separate buffers).
• The smuX.measure.count attribute determines how many measurements are
performed. When using a buffer, it also determines the number of readings to store
in the buffer.
Details See “Reading buffers” in Section 7.
Also see smuX.nvbufferY, smuX.nvbufferY
Example
Performs ten voltage measurements using SMU A and stores them in a buffer:
smua.measure.count = 10
smua.measure.v(smua.nvbuffer1)
smuX.measureYandstep
smuX.measureivandstep
X = SMU channel (a or b)
Y = SMU measure function (v, i, iv, r or p) where:
v = voltage, i = current, r = resistance, p = power
Function Performs one or two measurements and then steps the source.
Usage This function can be used in two ways:
reading = smuX.measureYandstep(sourcevalue)
readings = smuX.measureivandstep(sourcevalue)
reading Returns the measured reading before stepping the source.
readings Returns the two measured readings before stepping the source.
sourcevalue Source value to be set after the measurement is made.
