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 m easured over the entire waveform or gated region.
Max
The most positive peak voltage. Max is measured over the entire w aveform 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 w aveform 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 m ost common value found below the midpoint. This
value is measured over the entire w aveform 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% .
Total overshoot
This is the summation of the positive o vershoot and the negative overshoot.
