2. Tap the icon.
The overlay menu opens.
3. Set "Update" to the reference waveform to be used.
4. T
ap the waveform to be used as reference waveform.
To display a reference waveform
1. In the "Menu" > "Apps" > "Analysis" tab, select "Reference Curve".
Alternatively, press the [Ref] key.
2. Select the tab for the reference waveform you want to display ("R1"-"R4").
3. Load a stored reference waveform as described in "To load a reference waveform"
on page 251, or select a source to be displayed as a reference:
a) In the "Setup" tab, select "Signal".
b) Select the "Source" from the selection list. The source can be any active signal,
math, or other reference waveform.
c) Tap the "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. Additionally, it can be stretched or compressed in verti-
cal and horizontal direction.
If necessary, change the settings on the "Vertical" and "Rescale" tabs of the "Refer-
ence Waveform" dialog boxes.
To restore the original settings, tap the "Restore settings" in the "Vertical" tab.
For a description of the scaling settings, see Chapter 7.2.2.4, "Rescale",
on page 255
To save a reference waveform
1. In the "Save/Recall" dialog, select "Save > Waveform".
Tip: You can also save a waveform as a reference waveform in the "File" dialog
box, see Chapter 12.2.7, "Saving and loading waveform data", on page 473. Here,
you can also save multiple waveforms in one file.
2. Select the tab for the reference waveform you want to store ("Ref1"-"Ref4").
3. Display and configure the reference waveform as described in "To display a refer-
ence waveform" on page 250.
