smuX.nvbufferY
This attribute contains a dedicated reading buffer.
Type TSP-Link accessible Affected by Where saved Default value
Usage
bufferVar = smuX.nvbufferY
The dedicated reading buffer
Source-measure unit (SMU) channel (for example, smua.nvbuffer1 applies to
SMU channel A)
SMU nonvolatile buffer (1 or 2)
Details
Each SMU channel contains two dedicated reading buffers: smuX.nvbuffer1 and
smuX.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 smuX.savebuffer() function.
Example
smua.measure.overlappedv(smua.nvbuffer1)
Store voltage readings from SMU channel A
into SMU channel A dedicated reading
