Key Points
Upgrading Firmware. You can use the disk drive to upgrade the
oscilloscope firmware or install new application packages. See the
documentation provided with these packages for instructions.
Saved Waveform Formats. Use the Internal waveform format to save a
waveform to disk if you intend to recall it to the display later as a
reference waveform. Use the Spreadsheet format to create a
comma-separated data file compatible with most spreadsheet
programs. Use the Mathcad format if you intend to import the
waveform data into Mathcad software.
Navigating the File System. When you insert an IBM-formatted disk
and push the File Utilities screen button, the oscilloscope shows a list
of directories and files on the disk.
Use the general purpose knob to select a directory or file. To change
the working directory, select the directory and then push the
SELECT button. To move up one directory level, select .. and then
push the SELECT button.
Automatic File Numbering. The oscilloscope gives all files created by
the oscilloscope the default name TEK?????, where the question
marks are placeholders for an automatic number sequence from
00000 to 99999.
You can change the TEK????? file to a new name with up to eight
characters. If you use fewer than eight characters and include trailing
question marks, the oscilloscope numbers the files sequentially if
more than one are saved with the same base name.
For example, if you rename the TEK?????.ISF file to TEST??.ISF
for a series of saved waveforms, the oscilloscope saves the first one
as TEST00.ISF, the second one as TEST01.ISF, up to the last one as
TEST99.ISF.
