Step Sweep
In Step Sweep type, the output frequency of the instrument “steps” from “Start
Frequency” to “Stop Frequency”. The duration of the output signal on each frequency
point is determined by “Sweep Time” and “Step Number”.
When Sweep is enabled, press Type to select “Step”. A step waveform is displayed
on the waveform on the screen, indicating that the output frequency varies in “step”.
At this point, press to open the 2/2 menu page. Press Step Num and input the
step number using the numeric keyboard or direction keys and knob. The default is 2
and the range is from 2 to 1024.
Note: in “Linear” and “Log” sweep modes, Step Num is grayed out and disabled.
