The Full Screen measurement interval variation measures the value on all
displayed data points.
The N Cycles measurement interval variation measures the value on an
integral number of periods of the displayed signal. If less than three edges
are present, the measurement shows "No edges".
The X cursors show what interval of the waveform is being measured.
Measurement Thresholds
Setting measurement thresholds defines the vertical levels where
measurements will be taken on an analog channel or math waveform.
1 From the Measurement Menu, press the Settings softkey; then, press the
Thresholds
softkey to set analog channel measurement thresholds.
You can also open the Measurement Threshold Menu by pressing
[Analyze] > Features and then selecting Measurement Thresholds .

Changing default thresholds may change measurement results
The default lower, middle, and upper threshold values are 10%, 50%, and 90% of the value
between Top and Base. Changing these threshold definitions from the default values may
change the returned measurement results for Average, Delay, Duty Cycle, Fall Time,
Frequency, Overshoot, Period, Phase, Preshoot, Rise Time, +Width, and -Width.
