If the specified value for PulseWidth is outside of the allowable range, the
waveform generator will automatically adjust it to accommodate the
given pulse period.
Edge Time
The edge time represents the time from the 10% point to the 90% point
of an ascending or descending edge. The default edge time is 5 ns, and
the possible value is ranged from 5 ns to 100 ns, with the following
constraint on the maximum allowable value:
EdgeTime
≤
0.625 x PulseWidth
G5100A will alter the edge time when needed to accommodate the
specified pulse width.
Pulse Duty Cycle
Specifying pulse duty cycle is another way to define a pulse wave than
specifying pulse width. Pulse duty cycle is defined as follows:
DutyCycle = PulseWidth / PulsePeriod x 100%
If the specified pulse duty cycle conflicts with the specified pulse width or
vice versa, the most recently specified pulse duty cycle or pulse width will
be accepted over the other. The default duty cycle is 10%, and the
acceptable range is from 0% to 100%, with the following constraints:
DutyCycle
≥
Wmin / PulsePeriod x 100%
DutyCycle
≤
(1.0 - Wmin / PulsePeriod) x 100%
where Wmin is the minimum allowable value for pulse width defined in
the previous section on pulse width. The waveform generator will adjust
it to accommodate the given pulse period.
