The following figure shows time measurement points.
The default lower, middle, and upper measurement thresholds are 10%, 50%, and
90% between Top and Base values. See
for other percentage threshold and absolute value threshold settings.

Period
Period is the time period of the complete waveform cycle. The time is measured
between the middle threshold points of two consecutive, like-polarity edges. A
middle threshold crossing must also travel through the lower and upper threshold
levels which eliminates runt pulses. The X cursors show what portion of the
waveform is being measured. The Y cursor shows the middle threshold point.
