Measurement Description
Positive Duty Cycle 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.
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 first 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 first
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 first
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 phase angle difference of signals from two
different channels, using the rising edge of the
first signal compared to the rising edge of the
second signal. .

Measurement Description
Positive Overshoot This is measured over the entire waveform or
gated region and is expressed as:
Positive Overshoot = (Maximum – High) /
Amplitude x 100%.
Negative Overshoot This is measured over the entire waveform or
gated region and is expressed as:
Negative Overshoot = (Low – Minimum) /
Amplitude x 100%.
