Set Square Wave
The duty ratio of square wave represents time quantum of square wave at high level in each cycle (suppose waveform is
not reversed). The default duty ratio of square wave is 50% when powering on. The duty ratio is restricted by minimum
pulse width specification 10ns.
The specific steps for setting square wave with frequency of 1kHz, amplitude of
1.5Vpp, DC offset of 0V and duty ratio of 70% are as follows:
Press Square, Freq, Amp and Duty to set corresponding functions. Press the corresponding soft key to edit parameters,
then input the required value, and finally select the unit. Select corresponding value to set the duty ratio.

Note: this parameter can also be set with multi-functional control and direction key.
