Measurement Description
Negative Duty
Cycle The ratio of the negative pulse width to the signal period expressed as a percentage. The
duty cycle is measured on the
fi rst cycle in the waveform or gated region.
Positive Pulse
Width
The distance (time) between the mid reference (default 50%) amplitude points of a positive
pulse. The measurement is made on the
fi rst pulse in the waveform or gated region.
Negative Pulse
Width The distance (time) between the mid reference (default 50%) amplitude points of a negative
pulse. The measurement is made on the
fi rst pulse in the waveform or gated region.
Burst Width The duration of a burst (a series of transient events) and is measured over the entire
waveform or gated region.
Phase The amount of time that one waveform leads or lags another waveform, expressed in degrees
where 360° makes up one waveform cycle. See also
