Measurement Description
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. .

Positive
Oversh
oot
This i
s 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 w aveform or gated region and is
expr
essed as:
Negative Overshoot = (Low – Minimum) / Amplitude x 100%.
Pk-Pk
The absolute difference between the m aximum and minimum
amplitude in the entire waveform or gated region.
Amplitude The high value less the low value measured over the entire
waveform or gated region.
High
This value is used as 100% whenever high reference, mid
reference, or low reference v alues are needed, such as in fall time
or rise time measurements. Calculate using either the min/max
or histogram method. The min/max method uses the maximum
value found. The histogram method uses the most common value
found above the midpoint. This value is measured over the entire
waveform or gated region.
