Remote commands to configure traces:
●
The trace is the graphical representation of the measured spectrum. In the diagram, it
is represented by a colored graph. Depending on the trace configuration, the
R&S
FPC1000 evaluates and displays the measurement data differently.
Selecting a trace
The R&S
FPC1000 can display up to two traces at the same time, each with a different
configuration.
Before you configure a trace, you have to select the trace whose attributes you would
like to change.
1. Press the "Trace" key to open the trace menu.
2. Select the "Select Trace" menu item.
The currently selected trace number is highlighted.
Selecting a second trace
The R&S
FPC1000 can display two traces. Both traces are based on the same set-
tings, except the trace settings like 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
FPC1000 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
FPC1000 updates both traces based on their respective settings. The
trace information above the diagram area shows the settings for both traces.
