2.8 File recorder

The sat-nms M&C software provides a facility (a logical device) called File-Recorder which is capable to record arbitrary data like levels, antenna pointing etc. into a disc file. The File recorder page is the user interface to inspect such files. The page can be accessed either from the side toolbar File-Recorder menu or can be configured in user-screens on button-element as File-Recorder action.

Top toolbar

• MNC name: A dropdown to select the available MNC from drop-down.
• Device name: A dropdown to select the available file-recorder devices from drop-down.
• Reload: A button to reload the file-record data.

Title, live view, and configuration buttons

• Title: Displays the currently selected device name (e.g., "REC-SYS").

• Live view toggle: Beside for viewing stored log files, the File recorder Viewer can be used to display the logged data as it is acquired with an automated display update. By pressing the "live view" toggle button, the viewer changes to live view mode. In this mode the viewer shows up to 400 recent data points, automatically updated with an interval that is configurable separately from the standard interval at the device window setup (open config button).
