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
