To Set Pulse Width/Duty Cycle (Pulse)
Pulse width is defined as the time from the 50% threshold of a rising edge amplitude
to the 50% threshold of the next falling edge amplitude (as shown in the figure
below).
The setting range of pulse width is limited by the “Minimum Pulse Width” and the
“Pulse Period” (for the ranges of “Minimum Pulse Width” and “Pulse Period”, please
refer to “Signal Characteristics” in “Specifications”). The range of pulse width is
from 16ns to 999.999 982 118ks and the default value is 500μs.
 Pulse Width ≥ Minimum Pulse Width
 Pulse Width < Pulse Period - Minimum Pulse Width×2
Pulse duty cycle is defined as the percentage that the pulse width takes up in the
whole period.
Pulse duty cycle and pulse width are correlative. Once a parameter is changed, the
other will be automatically changed. Pulse duty cycle is limited by the “Minimum
Pulse Width” and the “Pulse Period”. The range of pulse duty cycle is from 0.001% to
99.999% and the default is 50%.
 Pulse Duty Cycle ≥ 100×Minimum Pulse Width ÷ Pulse Period
 Pulse Duty Cycle < 100×(1-2×Minimum Pulse Width÷Pulse Period)
Press Width/Duty to highlight “Width”. At this point, use the numeric keyboard to
input the desired pulse width value and then select the desired unit from the pop-up
menu.
 The pulse width units available are sec, msec, μsec and nsec.
 Press this softkey again to switch to duty cycle setting.
