Positive Duty Cycle
This timing measurement is the ratio of the positive pulse width to the signal period expressed as a
percentage.
The duty cycle is measured on the first cycle in the waveform or gated region.
Positive D uty Cycle = (Positive Width) × Period × 100%
Positive Width
This timing measurement is the distance (time) between the mid reference (default 50%) amplitude
points of a positive pulse.
The measurement is made on the first pulse in the waveform or gated region.
Negative Width measurement
This tim
ing measurement is the distance (time) between the mid reference (default 50%) amplitude
points of a negative pulse.
The mea
surement is made on the first pulse in the waveform or gated region.
Negat
iveDutyCycle
This timing measurement is the ratio of the negative pulse width to the signal period expressed as a
perc
entage. The duty cycle is measured on the first cycle in the waveform or gated region.
Negative Duty Cycle = (Negative Width) × Period × 100%
Period
This measurement is the time required to c omplete the first cycle in a waveform or gated region.
Period is the reciprocal of frequenc y and is measured in seconds.
Frequency
This timing measurement is a m easure of the first cycle in a waveform or gated region. Frequency is
the reciprocal of the period; it is measured in Hertz (Hz) where one Hz is one cycle per second.
Delay
This timing measurement is the time between the mid reference (default 50%) amplitude point
of two different waveforms
