Most result evaluations can also be used for zero span measurements, although some
functions (e.g. markers) may work slightly differently and some may not be available. If
so, this will be indicated in the function descriptions (see
Chapter 7.2.2, "Basic Evalua-
tion Methods" , on page 117).

Power Sweep
In a power sweep, the measured power levels at the RF input are displayed versus the
provided power levels of the internal generator output.
For a power sweep, the internal generator signal provides an output signal at a fixed
frequency, and increases its power level within a specified range over time.
The power sweep measurement is available in the Spectrum application only, and only
if the optional Internal Generator R&S
FPL1-B9 is installed.
For details see "Power Sweep Settings" on page 295.
Remote command:
SOURce<si>:POWer:MODE
on page 805
All Functions Off
Switches off all measurement functions and returns to a basic frequency sweep.
Selecting "Frequency Sweep" has the same effect.
7.2.1.2 How to Perform a Basic Sweep Measurement
The following step-by-step instructions demonstrate how to perform basic sweep mea-
surements.
For remote operation, see Chapter 11.6.17, "Programming Example: Performing a
Basic Frequency Sweep" , on page 747.
To perform one or more single sweeps
1. Configure the frequency and span to be measured ("Frequency" dialog box, see
Chapter 7.4, "Frequency and Span Configuration" , on page 301).
2. Configure the number of sweeps to be performed in a single measurement
("Sweep Config" dialog box, see "Sweep/Average Count" on page 326).
3. If necessary, configure a trigger for the measurement ("Trigger/ Gate Config" dialog
box, see Chapter 7.7, "Trigger and Gate Configuration" , on page 331).
4. Define how the results are evaluated for display ("Trace" dialog box, see Chap-
ter 7.10.1.2, "Trace Settings" , on page 393).
5. If necessary, configure the vertical axis of the display ("Amplitude" dialog box, see
Chapter 7.5, "Amplitude and Vertical Axis Configuration" , on page 307).
