smuX.buffer.recalculatestats()
This function recalculates the specified reading buffer's statistics.
Type TSP-Link accessible
Function Yes
Usage
smuX.buffer.recalculatestats(bufferVar)
X
bufferVar
Details
This function will cause the SMU to regenerate the reading buffer statistics on the specified reading buffer. As the
SMU automatically updates reading buffer statistics as 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
including only the data that is currently stored in the buffer.

Description
String indicating the function measured for the reading (current, voltage, ohms or
watts)
The full-scale range value for the measure range used when the measurement was
made
The reading value
String indicating the source function at the time of the measurement (current or
voltage)
String indicating the state of the source (off or on)
Full-scale range value for the source range used when the measurement was made
If bufferVar.collectsourcevalues is enabled, the sourced value in effect at
the time of the reading
Status value for the reading; the status value is a floating-point number that encodes
the status value into a floating-point value
If bufferVar.collecttimestamps is enabled, the timestamp, in seconds,
between when the reading was acquired and when the first reading in the buffer was
acquired; adding this value to the base timestamp will give the actual time the
measurement was acquired

Source-measure unit (SMU) channel (for example,
smua.buffer.recalculatestats() specifies SMU channel A).
