To Set Duty Cycle (Square)
Duty cycle is defined as the percentage that the high level takes up in the whole
period (as shown in the figure below). This parameter is only available when Square
or Pulse is selected.
The available range of the duty cycle is from 0.01% to 99.99% (limited by the
current frequency setting). The default is 50%.
Tap the Duty parameter input field to input the desired duty cycle value with the
numeric keypad, then select the unit "%". Tap "Ok".
You can also use the arrow keys and the knob to set the parameter value: press
down the knob to enter the editing mode, use the arrow keys to move the cursor to
select the digit to be edited, and then rotate the knob to modify the value. Besides,
you can use the knob to switch between different parameters.
