XY-Diagram
XY-diagrams combine the voltage levels of two waveforms in one diagram. They use
the amplitude of a second waveform as the x-axis, rather than a timebase. Thus, you
can measure phase shift, for example. With harmonically related signals, the resulting
XY-diagrams are Lissajous patterns. XY-diagrams can also be used to display the IQ
representation of a signal.
Together with the XY-diagram, the time diagrams of the source signals are displayed in
separate grids. It is also possible to define two source signals in y-direction for compar-
ison.
The XY-diagram is provided in a dedicated application on the R&S
RTB2000. If the XY-
application is active, reference waveforms are not available in all diagrams.
1. Press the
[Apps Selection] key.
2. Select "XY".
3. Make sure that the signals, the trigger, and the acquisition are set up correctly. The
required menus are available in XY-mode.
