Table 4: Amplitude measurements
Measurement Description
Peak-to-Peak The absolute difference between the maximum 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.
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 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. 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.
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 the midpoint. This value is measured
over the entire waveform or gated region.
Positive
Overshoot This is 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 waveform or gated region and is
expressed as:
Negative Overshoot = (Low – Minimum) / Amplitude x 100%.
