Math Waveforms

Maximum/Minimum
The Maximum operator is like the Max Hold operator without the hold. The
maximum vertical values found at each horizontal bucket are used to build a
waveform.
The Minimum operator is like the Min Hold operator without the hold. The
minimum vertical values found at each horizontal bucket are used to build a
waveform.
Peak-Peak
The Peak-Peak operator is like the Maximum operator minus the Minimum
operator. At each horizontal bucket, the minimum vertical values found are
subtracted from the maximum vertical values found to build a waveform.
Max/Min Hold
The Max Hold operator records the maximum vertical values found at each
horizontal bucket across multiple analysis cycles and uses those values to build a
waveform.
The Min Hold operator is the same, except it records the minimum vertical values.
When not used in a frequency analysis domain, these functions are often referred
to as Max Envelope and Min Envelope.
Press the Reset Count softkey to clear the number of waveforms evaluated.
Measurement Trend
The measurement trend math function shows measurement values for a waveform
(based on measurement threshold settings) as the waveform progresses across
the screen. For every cycle, a measurement is made, and the value is displayed on
the screen for the cycle.
