Step Sweep
The instrument "steps" through a list of frequencies during the sweep. The period that
the output signal dwells on each frequency is determined by "Sweep Time" and "Step
Number".
When the sweep type is set to "Step", click or tap the Step Num input field to set the
number of steps. It ranges from 2 (default) to 1024.

Start Frequency and Stop Frequency
The start frequency and stop frequency set the sweep's upper and lower frequency
bounds. The sweep begins at the start frequency, sweeps to the stop frequency, and
then resets back to the start frequency.
•
To sweep up in frequency, set the start frequency less than the stop frequency.
•
To sweep down in frequency, set the opposite relationship.
•
To sweep in a fixed frequency, set the same start frequency and stop frequency.
After enabling the sweep mode, click or tap the Start/Center button to set the
parameter to "Start". "Start" is now highlighted. This operation also toggles the
parameter of the Stop/Span button to "Stop". Click or tap the corresponding input
field and use the pop-up numeric keypad to set the start frequency and stop
frequency. By default, the start frequency is 100 Hz and the stop frequency is 1 kHz.
The range of start/stop frequency is related to the instrument model and wave type.
For details, refer to
After the start/stop frequency is modified, the instrument will sweep from the
specified start frequency again.
7.3
Center Frequency and Frequency Span
You can also set the sweep frequency boundaries of the sweep using a center
frequency and frequency span.
