Details
This function starts a measurement and returns immediately. The measurements, as they are performed, are
stored in a reading buffer (along with any other information that is being acquired). If the instrument is configured
to return multiple readings where one is requested, the readings are available as they are made. Measurements
are in the following units of measure: v = volts, i = amperes, r = ohms, p = watts.
The second form of this function, smuX.measure.overlappediv(), stores current readings in ibuffer and
voltage readings in vbuffer.
This function is an overlapped command. Script execution continues while the measurements are made in the
background. Attempts to access result values that have not yet been generated cause the script to block and
wait for the data to become available. The waitcomplete() function can also be used to wait for the
measurements to complete before continuing.
If a given reading buffer contains any data, it is cleared before taking any measurements, unless the reading
buffer has been configured to append data.
