Setting Step
Size and
Dwell Time
There are two ways to set the size of each step of
the step sweep—set the step size or set the number
of steps. The step size range is 1 kHz to the full fre-
quency range of the sweep generator (0.1 Hz to full
frequency range with Option 11); the number of
steps range is 1 to 10,000. The dwell time-per-step
of the step sweep can be set for any time in the
range of 1 ms to 99 sec. The step size and dwell
time-per-step parameters are set from the step
sweep ramp menu.
To go to the Step Sweep Ramp menu (shown below)
from the Step Sweep menu, press

This menu lets you set the dwell time, the step size,
the number of steps, and go to the trigger menu.
