Mixed Measurements
• "Area" on page 234
Area
Area measures the area between the waveform and the ground level. Area below
the ground level is subtracted from area above the ground level.
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.
T
Negative area
N cycles
Positive area
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.
