Step sweep allows you to enter RF output start and
stop frequencies and amplitudes, a number of
equally spaced points (steps) to dwell upon, and
the amount of dwell time at each point.
When a step sweep is activated, the signal
generator will sweep the RF output based on the
values entered for the parameters listed above. The
frequency, amplitude, or frequency and amplitude of
the RF output will sweep from the start amplitude/
frequency to the stop amplitude/frequency, dwelling
at equally spaced intervals defined by the [# Points]
softkey value for the configured step dwell time.
Step sweep provides a linear progression through
the start-to-stop frequency and/or amplitude values.
You can toggle the direction of the sweep up or down.
When the [Sweep Direction Down Up] softkey is set
to Up, values are swept from the start frequency/
amplitude to the stop frequency/amplitude. Set to
Down, values are swept from the stop frequency/
amplitude to the start frequency/amplitude.
NOTE Step sweep data cannot be saved to the instrument
state register or to the memory catalog.
List sweep allows you to create a list of frequency,
amplitude, and dwell time values and sweep the RF
output based on the entires in the List Mode
Values table.
Unlike a step sweep that contains linear ascending/
decending frequency and amplitude values spaced
at equal intervals throughout the sweep, list sweep
frequencies and amplitudes can be entered at
unequal intervals and nonlinear ascending/
decending or random order.
For convenience, the List Mode Values table can be
can be configured based upon the values of a previously
configured step sweep. Each step sweep point’s
associated frequency, amplitude and dwell time
values are entered ino a row in the List Mode Values
table, as the following example illustrates.
Configuring a swept RF output
The signal generator has two sweep
types: step and list.
Following an explanation of the dif-
ferences between step sweep and list
sweep, you will learn two ways to
configure the signal generator’s RF
output to sweep a defined set of fre-
quency, amplitude, and dwell time
points. You will create a step sweep
and then you will use these points
as the basis for a new list sweep.
NOTE Sweep data cannot be saved to the
instrument state register.
Step sweep data cannot be saved to the instrument
state register or to the memory catalog. Step
sweep configurations are reset at preset or when
the signal generator’s line power is cycled.
List sweep data cannot be saved within an
instrument state, but can be saved to the memory
catalog. For instructions on saving list sweep data,
see Storing Files in Part 4.
During swept RF output, the
FREQUENCY and
AMPLITUDE areas of the signal generator’s
display are deactivated.
