Fill mode
The fill mode setting for the reading buffer controls how the incoming data is managed as the buffer
fills. The options are:
Fill once: The buffer stops accepting data once it fills to capacity and no new data is stored in the
buffer.
Fill continuously: Data fills the buffer normally until the end of the buffer is reached. When the end
is reached, the data returns to the beginning of the buffer and overwrites the oldest reading. This
is a traditional circular buffer. In this case, the buffer never technically fills.
The following topics provide information about using the front panel to configure buffers and provide
an introduction to using remote commands to configure buffers.
For additional information about using remote commands for buffer operations, see the following
