offset, 30% duty cycle and 10 ° start phase. Refer to “To Output Sine
Waveform” to configure the parameters and output. This section will only talk about
“Duty Cycle”.
What’s Duty Cycle?
Duty Cycle is defined as the percentage that the high level takes up in the whole
period.
T
t Duty Cyc=t/T*100%
Set the Duty Cycle
1. Press Square to select square waveform. The key will be illuminated and the
corresponding menus display at the bottom of the screen.
2. Press Duty Cycle to highlight the softkey, and then use the numeric keyboard to
input “30” and select the unit “%” in the pop-up menu.
 The duty cycle range is limited by the “Freq/Period” setting.
For frequency lower than or equal to 10 MHz: 20％ to 80％
For frequency greater than 10 MHz and lower than or equal to 40 MHz: 40％
to 60％
For frequency greater than 40 MHz: 50％
 You can also use the knob to modify this parameter.
