pulse, you can work out this function.
3.12.1 Function Selection
: Choose pulse function, then press
〖
PulseParam
〗〖
PulseModDouble
〗
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:
8ns≤(first pulse width or time interval or second pulse width)
(first pulse width+ interval time +second pulse width) ≤(period-8ns)
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
modify pulse’s parameters with the sequence of second pulse width, interval time and first pulse
width.
3.12.5 Pulse State
: Press
〖
State
〗
to choose ‘Positive pulse’ ‘Negative pulse’ and ‘Plus-Negative
pulse’ alternatively. Positive pulse’s pulse width is positive value, pulse interval is 0 value.
Negative pulse’s pulse width is negative value, pulse interval is 0 value. Plus-Negative pulse’s
