Step Sweep
Mode
In step sweep frequency mode, the output frequency
changes in discrete, synthesized steps between se-
lected start and stop frequencies. Step sweeps can
be from a high frequency to a low frequency and
vice versa. The step size or number of steps between
the start and stop frequencies and the dwell time-
per-step are controllable from a step sweep menu.
