This changes the start frequency of the step sweep to 500 MHz.
6. Press >
Freq Stop 600
This changes the stop frequency of the step sweep to 600 MHz.
7. Press >
Ampl Start –20
This changes the amplitude level for the start of the step sweep.
8. Press >
Ampl Stop 0
This changes the amplitude level for the end of the step sweep.
9. Press > >
# Points 9
This sets the number of sweep points to nine.
10. Press >
Step Dwell 500
This sets the dwell time at each point to 500 milliseconds.
11. Press >
Return Sweep
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
softkey can also be used to abort a sweep in progress. To see the frequencies sweep again, press
to trigger the sweep.
Single 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
