Datasheet

Built-in waves have five types: Standard, Math, Linear, Combine and Special. Press

the option to enter into the waveform list and then select desired waveform by

left/right key or knob. Finally press〖Confirm〗to output selected waveform from the

output port, the sketch also be shown at the display.

Press 〖Back〗key to return to type menu and you can select other types of built-in

waveform again. Press〖Back〗key again to exit the built-in waveform menu. Or

press 【Waveform】key to return to current function window.

(3) The selected waveform diagram is shown but which is just a sample one with lower

resolution. Observe and test the output waveforms using oscilloscope.

5.2.2 Duty Cycle (Square or Pulse)

The duty cycle represents the fraction of time per cycle that the square wave is at a high

level. Press 【Waveform】key and choose Square or Pulse, press 〖Duty Cycle〗softkey

after selecting 【Continuous】key then set the desired value of duty cycle. Usually, the

duty cycle value remains unchanged if the Square frequency is changing, but duty cycle

is limited by the edge time if output frequency is too high, which should comply with the

below formula:

10ns ≤ ( Duty Cycle × Period ) ≤ ( Period－10ns )

5.2.3 Pulse Width and Edge Time

The pulse width represents the time from the 50% threshold of the rising edge of the

pulse to the 50% threshold of the next falling edge. After selecting the pulse function,

press the 〖Pulse Width〗 softkey. Then use the knob or numeric keypad to enter the

desired pulse width. The pulse width usually remains unchanged if the Square frequency

is changing, but will be limited by the edge time if output frequency is too high, which

should comply with the below formula:

10ns≤Pulse Width≤ Period－10ns

The edge time represents the time from the 10% threshold of rising/falling edge to 90%

of which. If select Pulse waveform in continuous menu, press 〖Edge Time〗 to select the

Edge parameter to set. The edge time setting will be also limited by pulse width, which

should comply with the below formula:

Edge Time≤0.625×Pulse Width

Edge Time≤0.625×Duty Cycle×Period
