Duty Cycle

Applies to square and pulse waveforms only. The duty cycle represents the amount of time per cycle that the waveform is at a high level (assuming that the waveform is not inverted).

20% Duty Cycle

80% Duty Cycle

  • Limits Due to Frequency: If the square wave or pulse function is selected and you change to a frequency that cannot produce the current duty cycle, the duty cycle is automatically adjusted to the maximum value for the new frequency.
  • The duty cycle setting does not apply to a square waveform used as the modulating waveform for AM, FM, PM, or PWM. The duty cycle setting applies only to a waveform carrier.
