Part IV: System Functions
Chapter 31: File Management
The ability to save and manipulate data is a key feature of using the DS2831 Digital TV Spectrum Analyzer.
From the File Management utility – accessible by pressing the
File
( ) key under the display – you can
delete, view, move, and sort data files saved to the system’s internal 1GB hard drive.
Files can also be transferred to a USB storage device. Simply connect the drive to the Type-A USB port on the
DS2831’s top panel, and look for the USB icon to appear in the status bar.
31-1 File Operations
In the file management menu, you can view all readable files currently saved to the DS2831’s internal hard
drive. These files are separated by type. Image files appear in one list, data files in another, and so on.
