Saving data
Saving data
The oscilloscope has internal memory locations where you can save instrument setups and waveforms. You can also save
screen images, setups, and waveforms to files on an external U SB drives.
Saving screen images to a file
Use this procedure to save a screen image to a file on a U SB drive. A s creen image is a ‘picture’ of the oscilloscope screen.
Screen imag
es are useful to include in reports or to compare w ith other screen images over time.
NOTE. A screen image is different than waveform data. A screen image is a picture of the screen, and does not contain any
data about the signals shown in the image. Waveform data is a file that contains the numeric values of all the sampled points
in a single
channel waveform. You cannot use a screen image file for further analysis, whereas you can load the data from a
waveform file into other oscilloscopes, or into PC-based analysis programs to perform advanced signal measurements.
1. Install a USB drive.
2. Set up the display to show the waveforms and other readouts that you want to save.
3. Push the Save/Recall front-panel button.
4. Push the Action side-menu button.
