Pulse Duty Cycle

The pulse duty cycle is defined as:

Duty Cycle = 100 ⋅ Pulse Width / Period

where 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 duty cycle: >0% to <100% (see restrictions below). The default is 50%.

•The specified pulse duty cycle must conform to the following restrictions determined by the minimum pulse width (Wmin). The U2761A will adjust the pulse duty cycle as needed to accommodate the specified period.

Duty Cycle ≥ 100 ⋅ Wmin / Period

and

Duty Cycle ≤ 100 ⋅ (1 – Wmin / Period)

where:

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.

Soft Front Panel Operation

After selecting Pulse at the top panel as shown in

Figure 2- 2, select Duty Cycle as shown in

Figure 2- 13 and input the desired pulse duty cycle value on the Duty Cycle panel.
