Time measurements (cont.)
Measurement Description
Negative Duty
Cycle
The ratio of the negative pulse width to t he signal period expressed as a percentage.
The duty cycle is measured on the first cycle in the waveform or gated region.
Burst Width
The duration of a burst (a series of transient events) and is measured over the entire
waveform or gated region.
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 w aveform 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 m
in/max or histogram method. The min/max method uses the maximum value found.
The histogram method uses the most c ommon value found above the midpoint. This
value is m easured over the entire waveform or gated region.
Low
This value is used as 0% whenever high reference, mid reference, or low reference
val
ues are needed, such as in fall time or rise time measurements. Calculate using either
the m in/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
va
lue is measured over the entire waveform o r gated region.
