Example
smua.nvbuffer1.collecttimestamps = 1 Include timestamps with readings for

Usage
fillCount = bufferVar .fillcount
bufferVar .fillcount = fillCount
fillCount The reading buffer fill count
bufferVar The reading buffer; can be a dynamically allocated buffer (user-defined), or a
dedicated reading buffer (such as
smua.nvbuffer1
)
Details
The reading buffer fill count sets the number of readings to store before restarting at index 1. If the value is zero
(0), then the capacity of the buffer is used. Use this attribute to control when the SMU restarts filling the buffer at
index 1, rather than having it restart when the buffer is full.
If the
bufferVar .fillcount
attribute is set to a value higher than the capacity of the buffer, after storing the
element at the end of the buffer, the SMU will overwrite the reading at index 1, the reading after that will
overwrite the reading at index 2, and so on.
This attribute is only used when the
bufferVar .fillmode
attribute is set to
smu X .FILL_WINDOW
.
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.fillcount = 50 Sets fill count of dedicated reading
buffer 1 (source-measure unit (SMU)
channel A) to 50.
