6.6. Buffer tab. Buffering and data downloading
Use this tab to manage the data buffer. The signal received by the application is buffered and stored
by the browser for the time specified by the Buffer time parameter.
The data that are currently contained in the buffer can be downloaded using the
Download
button.
Either all the data simultaneously or the data for each device can be downloaded.
Fig. 6.4. RT Viewer module. Buffering settings
Note that the buffer is used for making charts and tables. For example, to get a signal spectrum
containing data for a period of 5 minutes, the Buffer time parameter must exceed this value
(e.g., 10 minutes) so that there is enough data in the buffer to make the required chart. At the
same time, too much buffer value can lead to unstable operation of the web application due to
lack of RAM.
