b) To position the horizontal cursors automatically, select "Track waveform". In this
case, cursor 1 indicates the current maximum, cursor 2 indicates the current
minimum. If both horizontal and vertical cursors are displayed, the horizontal cur-
sors are placed at the crossing points of the vertical cursors with the waveform.
The vertical cursors must be positioned manually.
If the waveform arithmetics are set to "Envelope" and the "Trace Curve" setting
is enabled, select which horizontal cursor is positioned to the maximum and which
to the the minimum envelope values. Under "Envelope wfm selection 1", select
the crossing point for cursor 1. Under "Envelope wfm selection 2", select the
crossing point for cursor 2.
c) To maintain the distance between the vertical cursors when one cursor is moved,
select the "Coupling" option.
d) To set the cursors for a spectrum measurement to peak values automatically,
select the "Peak Search" tab.
Optionally, define a peak excursion, i.e. the minimum level value by which the
waveform must rise or fall so that it will be identified as a maximum or a minimum
by the search functions.
Tap one of the search function buttons to place the cursor(s) on the selected peak
value. For details see chapter 5.1.3.3, "Peak Search Tab", on page 127.
When you close the dialog box you can move the cursors on the touchscreen man-
ually; the results are adapted accordingly.
7. Optionally, select "Show in all diagrams" in the "Setup" tab to enable the cursor dis-
play for all waveform diagrams based on the same domain (time or spectrum) as the
selected source, for example a zoom or XY-diagram.
8. Tap the "Enable" icon in the "Setup" tab to activate the cursor measurement.
The cursors are displayed in the waveform diagram(s) of the measurement source
and the "Cursor" result box is displayed. For details on cursor measurement results,
see chapter 5.1.1, "Manual Measurements with Cursors", on page 121.
5.1.2.3 Configuring the Cursor Display
By default, the cursors are displayed as lines in the diagrams and labeled according to
the syntax:
C<cursor set number>.<1|2>
The cursors for the cursor set 3, for example, are labeled 3.1 and 3.2. Both the horizontal
and the vertical cursors have the same labels.
You can change the default cursor display.
1. Press the CURSOR key.
2. Select the "Cursor Style And Label" tab.
3. Select the tab for the cursor set you want to configure.
4. For each vertical and horizontal cursor enter a label to be displayed in the diagrams.
