Pulse Width
The pulse width represents the time from the 50% threshold of the
rising edge of the pulse to the 50% threshold of the next falling edge.
• Pulse width: 40 ns to 1000 s (see restrictions below). The default pulse
width is 100 µs.
• The minimum pulse width (Wmin) is affected by the period.
Wmin = 40 ns for period < 10 s.
Wmin = 200 ns for period > 10 s, but < 100 s.
Wmin = 2 µs for period > 100 s, but < 1000 s.
• The specified pulse width must also be less than the difference
between the period and the minimum pulse width as shown below.
The function generator will adjust the pulse width as needed to
accommodate the specified period.
Pulse Width < Period – Wmin
• The specified pulse width must be less than the difference between
the period and the edge time as shown below. The function generator
will automatically adjust the pulse width as needed to accommodate
the specified period.
Pulse Width < Period – (1.6 X Edge Time)
• The pulse width must also be greater than the total time of one edge
as shown below.
Pulse Width > 1.6 X Edge Time
• Front-Panel Operation: After selecting the pulse function, press the
Width
softkey. Then use the knob or numeric keypad to enter the
desired pulse width.
