Chapter 2 Front Panel Operations
To Set Pulse Width/Duty Cycle (Pulse)
Pulse width is defined as the time from the 50% threshold of a pulse's rising edge to
the 50% threshold of the next falling edge (as shown in the figure below).
tRise
The settable range of the pulse width is from 16 ns to 999.999982118 ks (limited by
"minimum pulse width" and "pulse period"). The default is 500 μs.
Pulse Width ≥ Minimum Pulse Width
⚫
Pulse Width < Pulse Period - 2 × Minimum Pulse Width
⚫
Pulse duty cycle is defined as the percentage that the pulse width takes up in the
whole pulse period.
Pulse duty cycle and pulse width are correlative. Modifying either of them (pulse duty
cycle or pulse width) will automatically affect the other. The settable range of the
pulse duty cycle is from 0.001% to 99.999% (limited by "minimum pulse width" and
"pulse period"). The default is 50%.
Pulse Duty Cycle ≥ 100 × Minimum Pulse Width ÷ Pulse Period
⚫
Pulse Duty Cycle < 100 × (1 - 2 × Minimum Pulse Width ÷ Pulse Period)
⚫
Tap the Width parameter input field to input the desired pulse width value with the
numeric keypad, then select the unit. Tap "Ok".
The pulse width units available are s, ms, μs, and ns.
⚫
Tap this menu label again to switch to duty cycle setting.
⚫
You can also use the arrow keys and the knob to set the parameter value: press
down the knob to enter the editing mode, use the arrow keys to move the cursor to
select the digit to be edited, and then rotate the knob to modify the value. Besides,
you can use the knob to switch between different parameters.
