Defining a trigger delay
When you are using an external trigger, you can delay the start of the measurement
with respect to the trigger event. Thus, you can include time differences between the
trigger event and the measurement.
1. Press the "Sweep" key to open the sweep menu.
2. Select the "Trigger" menu item to open the trigger menu.
3. Select the "Trigger Delay" menu item.
The R&S FPC opens an input field to define the delay time.
The range of the trigger delay is between 0 µs to 100 s. The resolution with which
you can select the delay time depends on the subrange of the delay time (see
Table 12-2).
Table 12-2: Trigger delay dependencies
Trigger delay Resolution
0 s to 1 ms 10 μs
1 ms to 10 ms 100 μs
10 ms to 100 ms 1 ms
100 ms to 1 s 10 ms
1 s to 10 s 100 ms
10 s to 100 s 1 s

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 FPC
evaluates and displays the measurement data differently.
Selecting a trace
The R&S FPC can display up to two traces at the same time, each with a different con-
figuration.
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.
