8.4 Reference waveforms
You can configure up to four reference waveforms to display stored waveforms. Any
active signal, mathematical waveform or spectrum can be stored as a reference wave-
form. It can then be loaded again later to restore the waveform on the screen.
8.4.1 Working with reference waveforms
Reference waveforms can be displayed in addition to the signal waveforms.
To display a reference waveform
1. In the "Menu" > "Apps" > "General" tab, select "Reference".
Alternatively, press the [Ref] key.
2. Select the tab for the reference waveform that you want to display ("R1/2/3/4").
3. Load a stored reference waveform as described in To load a reference waveform.
Alternatively, select a source to be displayed as a reference:
a) In the "Setup" tab, select "Source".
b) Select the "Source" from the selection list. The list shows all active waveforms
that can be saved as references.
c) Tap the "Create/update" button to update the current reference waveform with
the source data.
4. Tap the "Show" button.
The reference waveform is displayed on the screen.
5. A reference waveform can have its own scaling settings or it can be scaled accord-
ing to the source settings. By default, the scaling of the reference waveform is cou-
pled to the source settings. Also, it can be stretched or compressed in vertical and
horizontal direction.
If necessary, change the settings on the "Vertical" and "Rescale" tabs of the "Refer-
ence Waveform" dialog.
To restore the original settings, tap the "Set to original" in the "Vertical" tab.
For a description of the scaling settings, see Chapter 8.4.2.4, "Reference waveform
rescale", on page 181.
To load a reference waveform
1. Press the [Ref] key.
2. Select the tab for the reference waveform that you want to load ("R1/2/3/4").
3. In the "Setup" tab, select "Recall".
4. Select the file from the file selection dialog box.
