Setting the Output Frame Status
Use Samples per frame parameter to set the block’s output frame status, as
summarized in the table. The
Sample time parameter sets the sample time of
both sample- and frame-based outputs.
Shaping the Frequency Sweep by Setting Frequency Sweep and Sweep
Mode
The basic shape of the output instantaneous frequency sweep, f
i
(t), is set by the
Frequency sweep and Sweep mode parameters, described in the following
table.

Parameters for
Setting Sweep Shape
Possible Settings Parameter Description
Frequency sweep Linear
Quadratic
Logarithmic
Swept cosine
Determines whether the sweep frequencies vary
linearly, quadratically, or logarithmically.
(Linear and swept cosine sweeps both vary
linearly.)
Sweep mode Unidirectional
Bidirectional
Determines whether the sweep is unidirectional
or bidirectional. For details, see “Unidirectional
and Bidirectional Sweep Modes”.
