Criteria Used for Making Automatic Measurements
If more than one waveform, edge, or pulse is displayed, the measurements
are made on the first (leftmost) portion of the displayed waveform that can
be used. When any of the defined measurements are requested, the
oscilloscope first determines the top (100%) and base (0%) voltages of the
waveform. From this information, it can determine the other important
voltage values (10% voltage, 90% voltage, and 50% voltage) required to make
the measurements. The 10% and 90% voltage values are used in the rise time
and fall time measurements. The 50% voltage value is used for measuring
frequency, period, and pulse width.
