The currently selected trace number is highlighted.
Selecting a second trace
The R&S FPC can display two traces. Both traces are based on the same settings,
except the trace settings like the trace mode or the detector. You can use the second
trace to compare, for example, two different detector settings.
In the default state, only trace 1 is active.
1. Press the "Trace" key to open the trace menu.
2. Select the "Trace <x>" menu item.
The R&S FPC activates the second trace which has a different color than the first
trace.
After you have activated the second trace, this is also the active one. All actions
(like changing the detector or trace mathematics) apply to the active trace.
3. By default, the second trace has the trace mode "Blank". Before you can see it, you
have to select a different trace mode for the second trace.
4. Select the detector for the second trace.
The R&S FPC updates both traces based on their respective settings. The trace
information above the diagram area shows the settings for both traces.
