3.12 Double Pulse
There is one pulse in one pulse’s period. But in some applications, such as consecutively trigger
two relevant things according to certain intervals or test the time interval of two pulses,
specialized pulse signal generator will be required to generate double pulse signal. Choose double
pulse, you can work out this function.

to enter
double pulse function and display double pulse’s waveform diagram and its operation menu.
3.12.2 First pulse width
: Press
〖
Frist Width
〗
to set first pulse width. Pulse width means the lasting
time from rising edge’s middle point of first pulse to falling edge’s middle point.
3.12.3 Second pulse width
: Press
〖
Second Width
〗
to set second pulse width. Pulse width means
the lasting time from rising edge’s middle point of second pulse to falling edge’s middle point.
3.12.4 Interval Time:
Press
〖
Interval Time
〗
to set two pulses’ time interval. It means the lasting
time from falling edge’s middle point of first pulse to rising edge’s middle point of second pulse.
Two pulse width and time interval’s setting is limited not only by double pulse frequency, but also
by minimum time, which should conform to the following rules:
5ns≤(first pulse width or time interval or second pulse width)
(first pulse width+ interval time +second pulse width) ≤(period-5ns)
When pulse’s frequency or period changes according to above rules, the two pulse width and
interval time remains unchanged. If it can’t meet above rules, instrument will automatically
