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
waveform generator will adjust the pulse duty cycle as needed to
accommodate the specified period.
Duty Cycle >
100(16 ns) / Period
and
Duty Cycle <
100(1 – 16 ns / Period)
• The specified pulse duty cycle must conform to the following
restriction determined by the edge time. The waveform generator will
adjust the pulse duty cycle as needed to accommodate the specified
period.
• To achieve edges > 8.4 ns, the pulse width must be at least 20 ns. The
longer the edges, the greater the minimum pulse width. Longer edges
will therefore restrict duty cycle more than shorter edges.
• Front-Panel Operation: After selecting the pulse function, press
and toggle the
Width/Duty Cyc
softkey to
the Duty Cyc
softkey. Then press
, followed by
Duty Cycle
, and
use the knob
or numeric keypad to enter the desired duty cycle.
• Remote Interface Operation:
