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 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
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.
Pulse Width ≤ Period – Wmin
