Measurement Description
Min The most negative peak
voltage. Min is measured over
the entire waveform or gated
region.
High This value is used as 100%
whenever high reference, mid
reference, or low reference
values are needed, such as in
fall time or rise time
measurements. Calculated
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.
Low This value is used as 0%
whenever high reference, mid
reference, or low reference
values are needed, such as in
fall time or rise time
measurements. Calculated
using either the min/max or
histogram method. The min/
max method uses the minimum
value found. The histogram
method uses the most common
value found below the midpoint.
This value is measured over the
entire waveform or gated
region.
+Over This is measured over the
entire waveform or gated region
and is expressed as:
Positive Overshoot = (Maximum
– High) / Amplitude x 100%.
–Over This is measured over the
entire waveform or gated region
and is expressed as:
Negative Overshoot = (Low –
Minimum) / Amplitude x 100%.
Mean The arithmetic mean over the
entire waveform or gated
region.
