Yes
Usage
reading = smua.measure.Y()
reading = smua.measure.Y(readingBuffer)
iReading, vReading = smua.measure.iv()
iReading, vReading = smua.measure.iv(iReadingBuffer)
iReading, vReading = smua.measure.iv(iReadingBuffer, vReadingBuffer)
reading
Returned value of the last (or only) reading of the measurement process
Y
SMU measurement function (v = voltage, i = current, r = resistance, p = power)
readingBuffer
A reading buffer object where all readings are stored
iReading
The last reading of the current measurement process
vReading
The last reading of the voltage measurement process
iReadingBuffer
A reading buffer object where current readings are stored
vReadingBuffer
A reading buffer object where voltage readings are stored
Details
If you use this function without specifying a reading buffer, it makes one measurement and returns
that measurement as reading. To use the additional information that is acquired while making a
measurement or to return multiple readings, specify a reading buffer. If the instrument is configured to
return multiple readings for a measurement and readingBuffer is specified, all readings are
available in readingBuffer, but only the last measurement is returned as reading.
Measurements are in the following units of measure:
• v = volts
• i = amperes
• r = ohms
• p = watts
The smua.measure.iv() function returns the last actual current measurement and voltage
measurement as iReading and vReading, respectively. Additionally, it can store current and
voltage readings if buffers are provided (iReadingBuffer and vReadingBuffer ).
The smua.measure.count attribute determines how many measurements are performed. When
using a reading buffer, it also determines the number of readings to store in the buffer. If a reading
buffer is not specified, the SMU ignores the smua.measure.count attribute and only makes one
measurement.
The readingBuffer is cleared before making any measurements unless the buffer is configured to
append data.
Example
smua.measure.count = 10
smua.measure.v(smua.nvbuffer1)
Makes 10 voltage measurements using SMU channel A and
stores them in a buffer.
