Pulse Waveforms
A shown below, a pulse waveform consists of a period, a pulse width,
a rising edge, and a falling edge.
Pulse Period
• Pulse period: 20 ns to 2000 seconds. The default is 1 ms.
• The specified period must be greater than the sum of the pulse width
and the edge time as shown below. The function generator will adjust
the pulse width and edge time as needed to accommodate the
specified period.
Period >
Pulse Width + (1.6 X Edge Time)
• Function Limitations: If you change to a function whose minimum
period is greater than that for a pulse waveform, the period is
adjusted to the minimum value allowed for the new function.
For example, if you output a pulse waveform with a period of 50 ns
and then change to the ramp function, the function generator will
automatically adjust the period to 1 µs (the lower limit for ramps).
