WaveScan allows searching through a single acquisition for a
measurement parameter that meets a variety of conditions, or
scanning through multiple acquisitions with allowable trigger actions
when conditions are met. In addition, a variety of views can be used
to understand the specific behaviors of searched or
scanned measurement parameters. See Introduction to WaveScan
(on page 127 ) .
These capabilities are only possible with the measurement of every
occurrence of a measurement parameter in a long acquisition.
Both Track and Trend are tools that can be used to plot measurement data
and observe variations with respect to time. Differences between Track
and Trend are summarized in the following table:
Characteristic Track Trend
Representation Parameter value vs.
time Parameter value vs. event
Behavior Non-cumulative
(resets after every
acquisition).
Unlimited number
of events Cumulative over several
acquisitions up to 1 million
events
Time Correlation to
Other Data Yes No
Monitors an
Evolution in the
Frequency Domain Yes No. Trend points are not
evenly spaced in time and
therefore cannot be used for
an FFT.
Monitors the
Evolution of a
Measurement
Parameter over
Several Acquisitions No. Track resets
after every
acquisition. Yes
Ensures No Lost
Measurement Data Yes. Maximum time
period that can be No. Since data can be
accumulated over many
