Note: You can combine hardware zoom and normal zoom - first use the hardware
zoom, then the zoom into the display. The reverse approach is also possible: Cre-
ate a zoom diagram, and then apply the hardware zoom to the waveform diagram.
Both the waveform and the zoom diagrams are changed.
7.2 Reference waveforms
You can configure up to four reference waveforms to display stored waveforms. Any
active signal or mathematical waveform can be stored as a reference waveform. It can
then be loaded again later to restore the waveform on the screen.
7.2.1 Working with reference waveforms
Reference waveforms can be displayed in addition to the signal waveforms, saved to
file, and loaded back for further analysis. Reference waveforms can be loaded only
from BIN files.
Note: Saving and loading reference waveforms, and preset with active reference
waveform delete the undo stack. After these actions, undo is not possible.
To update a reference waveform using the toolbar icon
If you often need to update a reference waveform, you can use the "Update Ref Wfm"
toolbar icon.
1. Add the "Update Ref Wfm" icon to the toolbar, see Chapter 3.4.7.2, "Configuring
the toolbar", on page 119.
2. Touch the icon and open the icon menu.
3. Select the reference waveform to be used.
4. Tap the waveform to be used as reference waveform.
To display a reference waveform
1. In the "Math" menu, select "Reference Waveform > Setup", or press the [REF] key.
2. Select the tab for the reference waveform you want to display ("Ref1"-"Ref4").
3. Load a stored reference waveform as described in "To load a reference waveform"
on page 291, or select a source to be displayed as a reference:
