Usage
fillMode
=
bufferVar
.fillmode
bufferVar
.fillmode =
fillMode
fillMode
The reading buffer fill mode; set to one of the following:
0
or
smu
X
.FILL_ONCE
: Do not overwrite old data
1
or
smu
X
.FILL_WINDOW
: New readings restart at index 1 after acquiring
reading at index
bufferVar
.fillcount
bufferVar
The reading buffer; can be a dynamically allocated buffer (user-defined), or a
dedicated reading buffer (such as
smua.nvbuffer1
)
Details
When this attribute is set to
smu
X
.FILL_ONCE
, the reading buffer will not overwrite readings. If the
buffer fills up, new readings will be discarded.
When this attribute is set to
smu
X
.FILL_WINDOW
, new readings will be added after existing data until
the buffer holds
bufferVar
.fillcount
elements. Continuing the sequence, the next reading will
overwrite the reading at index 1, the reading after that will overwrite the reading at index 2, and so on.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the
reading buffer is saved to nonvolatile memory.
Example
smua.nvbuffer1.fillmode = smua.FILL_ONCE
Sets fill mode of dedicated reading buffer 1 (source-measure unit (SMU) channel A) to fill once (do not
overwrite old data).

buffer.

Usage
measurefunction
=
bufferVar
.measurefunctions[
N
]
measurefunction
The measurement function used (
"current"
,
"voltage"
,
"ohms"
, or
"watts
")
to acquire reading number
N
in the specified buffer
bufferVar
The reading buffer; can be a dynamically allocated buffer (user-defined), or a
dedicated reading buffer (such as
smua.nvbuffer1
)
N
The reading number (
1
to
bufferVar
.n
)
Details
The
measurefunctions
buffer recall attribute is like an array (a Lua table) of strings indicating the
function measured for the reading.
