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 8.6.14, "Programming Example: Performing a Basic
Frequency Sweep", on page 629.
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 375).
2. Configure the number of sweeps to be performed in a single measurement
( "Sweep Config" dialog box, see " Sweep/Average Count " on page 399).
3. If necessary, configure a trigger for the measurement ( "Trigger/ Gate Config" dia-
log box, see Chapter 7.7, "Trigger and Gate Configuration", on page 405).
4. Define how the results are evaluated for display ( "Trace" dialog box, see Chap-
ter 7.10.1.2, "Trace Settings", on page 466).
5. If necessary, configure the vertical axis of the display ( "Amplitude" dialog box, see
Chapter 7.5, "Amplitude and Vertical Axis Configuration", on page 381).
6. To start the measurement, select one of the following:
● RUN SINGLE key
● "Single Sweep" softkey in the "Sweep" menu
The defined number of sweeps are performed, then the measurement is stopped.
While the measurement is running, the RUN SINGLE key is highlighted. To abort
the measurement, press the RUN SINGLE key again. The key is no longer high-
lighted. The results are not deleted until a new measurement is started.
7. To repeat the same number of sweeps without deleting the last trace, select the
"Continue Single Sweep" softkey in the "Sweep" menu.
