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 10%.
– The specified pulse duty cycle must conform to the following restrictions
determined by the minimum pulse width (Wmin). The function generator 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.
– The specified pulse duty cycle must conform to the following restriction
determined by the edge time. The function generator will adjust the pulse duty
cycle as needed to accommodate the specified period.
Duty Cycle >
100 × (1.6 × Edge Time) ÷ Period
and
Duty Cycle <
100 × (1 – (1.6 × Edge Time) ÷ Period)
– Front-Panel Operation: After selecting the pulse function, press the Dty Cyc
softkey. Then use the knob or numeric keypad to enter the desired duty cycle.
