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
captured is limited
by acquisition
memory and
sampling rate. No. Since data can be
accumulated over many
acquisitions, and since the
oscilloscope takes time to
calculate measurement values
and to display data before the
trigger is re-armed, data can be
missed.
