(17) Pulse Width
Calculates the time between the waveform crossing the specified level in
the selected direction and crossing in the opposite direction.
Obtains the pulse width of the waveform within the range for calculation
and selects the maximum and minimum values.
(Maximum pulse width) = max{T
i
}(i=1, 2, 3...)
(Minimum pulse width) = min{T
i
}(i=1, 2, 3...)
The diagram below shows an up-slope case. When UP is selected, the
width of the "H" pulse is calculated, and when DOWN is selected, the
width of the "L" pulse is calculated.
(18) DUTY
Obtains the time from when a wave rises and crosses the specified level to
when it falls and crosses the specified level. Obtains the time from when a
wave falls and crosses the specified level to when it rises and crosses the
specified level. Determines the ratio using both time measurements.
Obtains the duty ratio of the waveform within the range for calculation
and selects the maximum and minimum values.
(Maximum duty ratio) = max{T
i
}(i=1,2,3...)
(Miminum duty ratio) = min{T
