You used the Sweep step to specify a range of values to iterate through
the Frequency parameter of the Create Signal step. The Create Signal
step uses the defined frequency range to generate a sine wave at each
of these frequencies. However, you can use the Sweep step to sweep
any sweepable parameter value of any sweepable step in a project.
