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 Not applicable
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.
