To Output Pulse Waveform

To output a pulse waveform from CH1 with 20 kHz frequency, 2.5 Vpp amplitude, 500

DC offset, 10 μs pulse width (20% duty cycle), 50 ns leading and trailing edge time

and 8 μs delay. Refer to “To Output Sine Waveform” to configure the parameters

and output. This section will only talk about “Width/Duty”, “Leading”, “Trailing”,

“Delay” and “Restore”.

Pulse Width/Duty Cycle

Pulse Width is defined as the time from the 50% threshold of a leading edge

amplitude to the 50% threshold of the next trailing edge amplitude as shown in the

figure above. Duty Cycle is defined as the percentage that the pulse width takes up in

the pulse period.

Press Pulse  Width/Duty to highlight “Pulse Width”, and then use the numeric

keyboard to input “10” and select the unit “μsec” in the pop-up menu.

 Pulse Width is limited by the “Minimum Pulse Width” and the “Pulse Period”.

Minimum Pulse Width = 4 ns

Pulse Width ≥ Minimum Pulse Width

Pulse Width ≤ Pulse Period - Minimum Pulse Width × 2

 Pulse Width and Duty Cycle are correlative. Once a parameter is changed, the
