0 (smuX.FILL_ONCE)
Usage
fillMode = bufferVar.fillmode
bufferVar.fillmode = fillMode
fillMode
The reading buffer fill mode; set to one of the following:
▪ 0 or smuX.FILL_ONCE: Do not overwrite old data
▪ 1 or smuX.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 smuX.FILL_ONCE, the reading buffer does not overwrite readings. If the
buffer fills up, new readings are discarded.
When this attribute is set to smuX.FILL_WINDOW, new readings are added after existing data until
the buffer holds bufferVar.fillcount elements. Continuing the sequence, the next reading
overwrites the reading at index 1, the reading after that overwrites 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 to fill once (do not overwrite old data).

reading buffer.
