Measurement
Description
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.
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.
Mean
The arithmetic mean amplitude over the entire waveform or gated
region.
Cycle
Mean
The arithmetic mean over the
fi
rst cycle in the waveform or the
fi
rst cycle in the gated region.
RMS
The true Root Mean Square voltage over the entire waveform or
gated region.
Cycle
RMS
The true Root Mean Square voltage over the
fi
rst cycle in the
waveform or the
fi
rst cycle in the gated region.
Miscellaneous measurements
Measurement
Description
Rising
Edge
Count
The number of positive transitions from the low reference value to
the high reference value in the waveform or gated region.
Falling
Edge
Count
The number of negative transitions from the high reference value to
the low reference value in the waveform or gated region.
