Basic Operation
Configuring the RF Output
To Configure a Continuous Step Sweep
Press
Sweep Repeat Single Cont.
This toggles the sweep from single to continuous. A continuous repetition of the frequencies and
amplitudes configured in the step sweep are now available at the RF OUTPUT connector. The SWEEP
annunciator appears on the display, indicating that the signal generator is sweeping and progression
of the sweep is shown by a progress bar.
Using List Sweep
List sweep enables you to create a list of arbitrary frequency, amplitude, and dwell time values and
sweep the RF output based on the entries in the List Mode Values table.
Unlike a step sweep that contains linear ascending/descending frequency and amplitude values,
spaced at equal intervals throughout the sweep, list sweep frequencies and amplitudes can be entered
at unequal intervals, nonlinear ascending/descending, or random order.
For convenience, the List Mode Values table can be copied from a previously configured step sweep.
Each step sweep point’s associated frequency, amplitude and dwell time values are entered into a
row in the List Mode Values table, as the following example illustrates.
To Configure a Single List Sweep Using Step Sweep Data
In this procedure, you will leverage the step sweep points and change the sweep information by
editing several points in the List Mode Values table. For information on using tables, see “Using Table
Editors” on page 34.
1. Press
Sweep Repeat Single Cont.
This toggles the sweep repeat from continuous to single. The SWEEP annunciator is turned off. The
sweep will not occur until it is triggered.
2. Press
Sweep Type List Step.
This toggles the sweep type from step to list.
3. Press
Configure List Sweep.
This opens another menu displaying softkeys that you will use to create the sweep points. The
display shows the current list data. (When no list has been previously created, the default list
contains one point set to the signal generator’s maximum frequency, minimum amplitude, and a
dwell time of 2 ms.)
4. Press
More (1 of 2) > Load List From Step Sweep > Confirm Load From Step Data.
The points you defined in the step sweep are automatically loaded into the list.
To Edit List Sweep Points
1. Press
Return > Sweep > Off.
Turning the sweep off allows you to edit the list sweep points without generating errors. If sweep
remains on during editing, errors occur whenever one or two point parameters (frequency, power,
and dwell) are undefined.
2. Press
Configure List Sweep.
This returns you to the sweep list table.
