smuX.nvbufferY
This attribute contains a dedicated reading buffer.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (R) Yes Not applicable See
Details

Usage
bufferVar = smu X .nvbuffer Y
bufferVar The dedicated reading buffer
X Source-measure unit (SMU) channel (for example,
smua.nvbuffer1
applies to
SMU channel A)
Y SMU nonvolatile buffer (
1
or
2
)
Details
Each SMU channel contains two dedicated reading buffers:
smu X .nvbuffer1
and
smu X .nvbuffer2
.
All routines that return measurements can also store them in either reading buffer. Overlapped measurements
are always stored in a reading buffer. Synchronous measurements return either a single-point measurement or
can be stored in a reading buffer if passed to the measurement command.
The dedicated reading buffers can be saved to internal nonvolatile memory (to retain data between power
cycles) using the
smu X .savebuffer()
function.
Example
smua.measure.overlappedv(smua.nvbuffer1) Store voltage readings from SMU channel A
into SMU channel A dedicated reading
buffer 1.
