The duty cycle range is limited by the "Frequency/Period" setting. Please refer to
"Signal Characteristics" in Specifications. The default value is 50%.
Press [Wave] > Square softkey to select the square waveform function and press Duty
softkey to highlight it. At this point, use the numeric keypad to input the value and select
the unit "%" from the unit menu that pops up, or use the direction keys and the knob to
modify the current value. For the input method of duty cycle value, refer to the
introduction in "Parameter Setting Method".
5.2.7 Set the Symmetry
Symmetry is defined as the percentage that the rising period takes up in the whole
period as shown in the figure below. This parameter is only available when ramp is
selected.
Symmetry can be set in the range of 0% to 100%. The default value is 50%.
Press [Wave] > Ramp softkey to select the ramp wave function and press Symmetry
softkey to highlight it. At this point, use the numeric keypad to input the value and select
the unit "%" from the unit menu that pops up, or use the direction keys and the knob to
modify the current value. For the input method of symmetry value, refer to the
introduction in "Parameter Setting Method".
5.2.8 Set the Pulse Parameters
To output a pulse, users need to set the "Width/Duty", "Leading" and "Trailing", in
addition to the basic parameters (such as the frequency, amplitude, DC offset voltage,
high level, low level and align phase) introduced above.
