smuX.measure.Y
smuX.measure.iv
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)

• This function returns only the last actual measurement as
Remarks
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

• The
performed. When using a buffer, it also determines the number of readings to store
in the buffer.
Details See "Reading
Also see smuX.nvbufferY,
Performs ten voltage measurements using SMU A and stores them in a buffer:
Example
smua.measure.count = 10
smua.measure.v(smua.nvbuffer1)
smuX.measureYandstep
smuX.measureivandstep
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)
