2. Select the subtab for the measurement group you want to configure.
3.
Under "Long term"
, tap "Enable".
4. Since the waveform can change in the process of time, enable "Continuous auto
scale" to adapt the scaling automatically.
Alternatively, tap the "Auto scale" to adjust the scale once and to see the long-term
waveform.
5. Tap "Horizontal scaling".
6. Define the "Number of points" to be shown in the long-term diagram.
7. Set the "Scale mode" that defines the period of time from which one long-term
point is created.
See "Scale mode" on page 362 for setting details.
For each long-term measurement point, the current measurement value is added
to the long-term waveform.
8. If you need the statistical data of the long-term points:
a) Tap "Result Analysis" to return to the measurement settings.
b) Enable statistics.
c) Let the measurement run and export the data when finished.
8.2.12.3 Histograms on measurement results
Histograms are available not only for channel, math and reference waveforms, but also
on measurement results. These histograms cannot be configured, and they are shown
in a separate diagram. The source is a measurement, and all events in all acquisitions
are are measured and included in the histogram. If the histogram is based on long-
term measurement, it is shown in the long-term diagram.
See also: "Enable (Histogram)" on page 360.
8.2.12.4 Track
The track is a waveform that shows measurement values in time-correlation to the
measured signal. It is the graphical interpretation of all measurement values of a single
acquisition.
The track is available for most amplitude/time measurements (except for High, Low,
Amplitude, Max, Min, Peak to peak, Mean, RMS, S-dev, Pos. and Neg. overshoot, and
Area), and for jitter measurements.
Enabling the track enables also the Continuous auto scale and Measure all events in
each acquisition.
To analyze the track, you can use cursor measurements and zoom.
