Buffervar.readings - Keithley 2601B Reference Manual

Series 2600B System SourceMeter® Instrument Reference Manual
Details
This read-only attribute contains the number of readings presently stored in the buffer.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the reading buffer
is saved to nonvolatile memory.
Example
numberOfReadings = smua.nvbuffer1.n
print(numberOfReadings)

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.

Clearing the buffer
The value of the reading in the specified reading buffer
The reading buffer; can be a dynamically allocated user-defined buffer or a
dedicated reading buffer
The reading number (1 to bufferVar.n)
Section 7: TSP command reference
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.
