In peak detect acquisition mode, the number of values depends on the decimation fac-
tor. If the decimation factor is 1, one value per sample is written. At higher decimation
factors, two values per sample are written.
In CSV files, the data values of one sample are written in one row. Envelope data, for
example, looks like this:
-0.0125490196078431 -0.0619607843137255
-0.0133333333333333 -0.0627450980392157
-0.0149019607843137 -0.0650980392156863
XML files are easy to read:

4.6 XY-Diagram
XY-diagrams combine the voltage or current levels of two input signals in one diagram.
They use the level of a second signal as the x-axis, rather than a time base. This
allows you to perform phase shift measurements, for example.
1. Press the [Mode] key.
2. Select "XY".
3. Make sure that the signals, the trigger, and the acquisition are set up correctly. The
following menus are available in XY-mode:
● "Vertical", see Chapter 3.2, "Vertical Setup" , on page 40.
● "Horizontal", see Chapter 3.3, "Horizontal Setup" , on page 45.
● "Trigger", see Chapter 3.6, "Trigger" , on page 50.
● "Acquire", see Chapter 3.4, "Acquisition Control" , on page 46.
To analyze the signal in XY-mode, you can use cursor measurements. You can select
vertical or horizontal cursors, couple the cursor lines or set them to screen. All other
cursor settings are not relevant for measuring the XY-diagram.
