4. To save the waveform to the currently selected file, select "Save". By default, the
prefix for reference waveform files is "RefCurve".
To save the waveform to a new file, select "Save As" and enter a file name, then
select the directory and file type. In order to load the reference waveform on the
instrument again later, use the file type .bin or .xml.
The source settings of the reference waveform and the current scaling settings are
stored to the specified file.
To load a reference waveform
1. In the "Math" menu, select "Reference Waveform > Setup", or press the REF key.
Tip: Alternatively, you can load a waveform as a reference waveform from the
"File" dialog box, see chapter 12.1.2, "Saving and Loading Waveform
Data", on page 345.
2. Select the tab for the reference waveform you want to load ("Ref1"-"Ref4").
3. To re-load the currently selected file, tap the "Load" button.
To open a new file, tap the "Open" button. In the file selection dialog box, select the
file that contains the reference waveform (file type .bin or .xml) and tap "Select".
The reference waveform with its stored settings is loaded.
4. Tap the "Show reference waveform" icon to display the reference waveform.
7.2 Reference Waveforms
To compare waveforms and analyze differences between waveforms, you can use up to
four reference waveforms R1 to R4. Each reference waveform has its own memory on
the instrument. You can also save an unlimited number of reference waveforms and load
them for further use.
The display of a reference waveform is independent from that of the source waveform;
you can move, stretch and compress the curve vertically and horizontally. Reference
waveforms are configured in the "Reference Waveform" dialog box, which is displayed
when you press the REF key or select "Math > Reference curves" from the menu.
7.2.1 Reference tab
In the "Reference" tab, you select the reference waveform and its source.The source is
an active waveform - trace of an input channel, math waveform or another reference
waveform - or a stored waveform.
