Example
numberOfReadings = smua.nvbuffer1.n
print(numberOfReadings)
Reads the number of readings stored in dedicated reading buffer 1 (source-measure unit (SMU) channel A).
Output:
1.25000+02
The above output indicates that there are 125 readings stored in the buffer.

bufferVar.readings
This attribute contains the readings stored in a specified reading buffer.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (R) Yes Clearing the buffer See Details Not applicable
Usage
reading = bufferVar .readings[ N ]
reading The value of the reading in the specified reading buffer
bufferVar
The reading buffer; can be a dynamically allocated user-defined buffer or a
dedicated reading buffer
N The reading number
N
; can be any value from 1 to the number of readings in the
buffer; use the
bufferVar. n
command to determine the number of readings in the
buffer
Details
The
readings
buffer recall attribute is like an array (a Lua table) of the readings stored in the
reading buffer. This array holds the same data that is returned when the reading buffer is accessed
directly; that is,
rb[2]
and
rb.readings[2]
access the same value.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the
reading buffer is saved to nonvolatile memory.
