Basic Operation
Configuring the RF Output
This changes the start frequency of the step sweep to 500 MHz.
6. Press Freq Stop > 600 > MHz .

This changes the stop frequency of the step sweep to 600 MHz.
7. Press Ampl Start > –20 > dBm .

This changes the amplitude level for the start of the step sweep.
8. Press Ampl Stop > 0 > dBm .

This changes the amplitude level for the end of the step sweep.
9. Press # Points > 9 > Enter .

This sets the number of sweep points to nine.
10. Press Step Dwell > 500 > msec .

This sets the dwell time at each point to 500 milliseconds.
11. Press Return > Sweep > Freq & Ampl .
This sets the step sweep to sweep both frequency and amplitude data. Selecting this softkey
returns you to the previous menu and turns on the sweep function.
12. Press RF On/Off .

The display annunciator changes from RF OFF to RF ON.
13. Press Single Sweep .
A single sweep of the frequencies and amplitudes configured in the step sweep is executed and
available at the RF OUTPUT connector. On the display, the SWEEP annunciator appears for the
duration of the sweep and a progress bar shows the progression of the sweep. The
Single Sweep
softkey can also be used to abort a sweep in progress. To see the frequencies sweep again, press
Single Sweep to trigger the sweep.
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
