DSA800 USB file limit

Posted on: December 16th, 2020 by James

On the DSA800 series with current firmware up to version 1.18 there is a known limit on the number of files that can be shown when viewing a USB stick’s content on the instrument front panel.

This limit is 50 files or directories. Once this number is reached additional files will not be shown in the file browser. This can cause an issue if you are saving a lot of limit, setup, or data files that you want to open later on the analyzer itself. This can also cause an issue when trying to load firmware on a full memory stick.

To make certain all your files can be viewed or opened on the analyzer we suggest separating files into folders so that no single directory has more than 50 items in it.
