smuX.buffer.recalculatestats()
This function recalculates the statistics of the specified reading buffer.
Type TSP-Link accessible
Function Yes
Usage
smuX.buffer.recalculatestats(bufferVar)
X
bufferVar
Details
This function causes the SMU to regenerate the reading buffer statistics about the specified reading
buffer. Because the SMU automatically updates reading buffer statistics when data is added to the
reading buffer, this function is generally not needed. When the reading buffer is configured to wrap
around and overwrite older data with new data, the buffer statistics will include the data that was
overwritten. Use this function to recalculate the statistics that include only the data that is presently
stored in the buffer.

smuX.cal.adjustdate
This attribute stores the date of the last calibration adjustment.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
adjustDate = smuX.cal.adjustdate
smuX.cal.adjustdate = adjustDate
adjustDate
X
Details
This attribute stores the adjustment date associated with the active calibration set. The adjustment
date can be read at any time, but can only be assigned a new value when calibration has been
enabled with the smuX.cal.unlock() function.
You cannot change the adjustment date without first making a change to the calibration constants.
Once you change any calibration constants, you must set the adjustment date before you can save
the calibration data to the nonvolatile memory of the SMU.
