Amplitude Measurements (cont.)
Measurement Description
Pk-Pk
The absolute difference betwee n the maximum and minimum amplitude in the entire
waveform or ga ted 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
values are needed, su ch as in fall time or rise time measurements. Calculate using either
the min/max or hist ogram 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 th e 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. Calculate 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 th e midpoint. This value is measured
over the entire waveform or gated region.
Max
The most positive peak voltage. Max is measured over the entire waveform or gated region.
Min
The most negative peak voltage. Min is measured over th e entire waveform or g ated region.
