Basic Waveform Output EN 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.
