Amplitude Measurements (cont.)
Measurement Description
Pk-Pk
The absolute difference between the maximum and minimum amplitude in the entire
waveform or ga ted region.
Amplitude
The high value less the low value measured over t he entire waveform or gated region.
High
This value is used as 100% whenever high reference, mid refe rence, or low r eference
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 hist ogram 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/ma x
or histogram method. The min/ma x method uses the minim um value found. The histogram
method uses the most common value found below th e m idpoint. This value is measured
over the entire wa v eform or gated region.
Max
The mo st positive peak voltage. Ma x is measured over the entire waveform or gated region.
Min
The mo s t negative peak voltage. Min is measu red over the entire waveform or gated region.
