Measurement Description
Pk-Pk
The absolute difference between the maximum and minimum a mplitude in the entire
waveform or gate d region .
Amplitude
The high value less the low value mea sured 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 measu remen ts. Calculate using either
the min/max or histogram m e thod. 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. Calculate using either the min/max
or h istogram m et hod. The min/max method uses the minimum value found. The histogram
method uses the m ost common value fou nd below the midpo int. This value is measured
over the entire wave form or gated region.
Max
The most positive peak voltage. Max is m easured over the entire waveform or gated region.
Min
The most negative peak voltage. Min is measured over the entire waveform or gated region.
