Example
measurerange = smua.nvbuffer1.measureranges[1]
Store the measure range that was
used to make reading number 1.
printbuffer(1, 10, smua.nvbuffer1.measureranges) Print the range values that were used
for the first 10 readings saved in
dedicated reading buffer 1.
Example output:
1.00000e-07, 1.00000e-07,
1.00000e-07, 1.00000e-07,
1.00000e-07, 1.00000e-07,
1.00000e-07, 1.00000e-07,
1.00000e-07, 1.00000e-07

Usage
numberOfReadings
=
bufferVar
.n
numberOfReadings
The number of readings stored in the buffer
bufferVar
The reading buffer; can be a dynamically allocated user-defined buffer or a
dedicated reading buffer
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)
Reads the number of readings stored in
dedicated reading buffer 1.
Output:
1.25000+02
The above output indicates that there are 125
readings stored in the buffer.
