Using the USB Fil
e Utility functions
Formatting the USB drive
Formatting a USB drive removes the file and directory names from the drive, making the entire USB drive memory available
for new files and folders.
CAUTION. Formatting a USB drive does not remove the data on the drive. It deletes the FAT table entries for the names of
the files and folders and marks the memory as available. If you have critical or secure data that must be removed from the
USB drive, connect the USB drive to a PC and use a file ‘shredding’ program to replace the file data with zeros.
1. Push the Save/Recall front-panel button.
2. Push the File Utility side-menu button.
3. Push the Format side-menu button.
4. Use the Multipurpo se knob to select and click Yes. The oscilloscope formats the drive and reopens the file utility pane.

utomatically generated file names
The oscilloscope automatically creates a numbered file name for the files that it saves to the USB drive.
The naming convention is TEKXX XXX.<ext>, where:
XXXXX is an integer from 00000 to 99999
<.ext> is the file type (.PNG, .BMP, or .JPG for screen image files; .SET for setup files; .ISF or .CSV for waveform files)
To create a new file name, the oscilloscope scans the USB drive to determine the highest-numbered file name present for the
file type being saved. The oscilloscope then increments that number and uses it for the new file name. For example, the
first time y ou save a file, the oscilloscope creates the file name TEK00000. The next time you save the same type of file,
the new file is named TEK00001.
Image, setting, and w ave form file tips
If t
here are nonsequential jumps in the fi le numbering, such as TEK00001, TEK00002, TEK00005, the oscilloscope uses
the highest-numbered file as the starting point for new file names (TEK00006 in this example).
If you select a different USB drive or folder location, the oscilloscope creates the file number based on the files
present in that USB d rive or folder. For example, if you select the save folder as /usb0/MyProject1, which contains file
TE
K00006.png, the next saved .png file in that folder is named TEK00007.png.
To
determine the channel or waveform type (Math, FFT, Ref) of a saved waveform file, open the waveform file (.CSV or
.ISF) in a text editor. The channel name or waveform type is at or near the top of the file structure.
