Recalling waveform data
Use this procedure to recall (load) waveform data from an external .ISF file to load into a reference memory location and
display on the oscilloscope. The oscilloscope can only load .ISF waveform data files.
NOTE. 20M record length waveforms cannot be loaded into reference memory, either directly from the oscilloscope or from
a saved file. All other record length waveforms can be loaded into reference memory.
1. Install a USB drive that contains the .ISF waveform data file.
2. Push the Save/Recall front-panel button.
3. Push the Action side-menu button.

7. Push Select File side-menu button to open the File Utility pane.
8. Use the M ultipu rpo se knob to select the waveform file (*.ISF).
9. Push Recall side-menu button. The oscilloscope loads the waveform data into the selected reference memory.
NOTE. If the Recall side-menu button shows No file, then you have not selected an .ISF file.
