Pulse Width
The pulse width represents the time from the 50% threshold
of the pulse’s rising edge to the 50% threshold of the next
falling edge.
• The range of the pulse width is 40 ns to <2000 s (see
restrictions below). The default pulse width is 500
μ
s.
• 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
Wmin = 20 μs for period > 1000 s
• The specified pulse width must also be less than the
difference between the period and the minimum pulse
width as shown in the equation below. The U2761A will
adjusts the pulse width as necessary to accommodate the
specified period.

Soft Front Panel Operation
After selecting Pulse at the top panel as shown in
Figure 2-2, on the Width panel below, input the desired
pulse width value and select the unit from the drop down
list.
