smuX.measure.Y
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 more measurements.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage
There are three ways to use this function:
reading = smuX.measure.v()
reading = smuX.measure.v(rbuffer)
reading = smuX.measure.i()
reading = smuX.measure.i(rbuffer)
reading = smuX.measure.r()
reading = smuX.measure.r(rbuffer)
reading = smuX.measure.p()
reading = smuX.measure.p(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
attribute determines how many measurements are performed.
When using a buffer, it also determines the number of readings to store in the buffer.

Example
Performs ten voltage measurements using SMU A and stores them in a buffer:
smua.measure.count = 10
smua.measure.v(smua.nvbuffer1)
