Analysis scale
The measurement scale of a long-term measurement diagram or measurement histo-
gram can be set automatically by the instrument, or manually.
Use automatic scaling if the measurement is running and you cannot see the expected
results.
"Continuous auto scale"
Performs an automatic scaling whenever the long-term waveform or
the histogram does not fit in the diagram during the measurement
period.
"Vertical"
Defines the vertical scaling per division for long-term measurement
period and the measurement histogram.
"Offset"
Defines an offset for the long-term measurement and the measure-
ment histogram.

Measure all events in each acquisition
Normally, only one measurement is performed for each acquired waveform to get best
performance. If "Measure all events in each acquisition" is enabled, more than one
result is taken from one acquired waveform and the results are included evaluation.
For example, the rise time is measured on all pulses in the waveform, not only on the
first.
The result box shows only the first result of the waveform, the following results are
used only for evaluation.
All event results are also considered in limit and margin checks and can initiate an
action. However, the icons in the result box only indicate violations of the first result.
Measuring all events is enabled automatically when calculating statistics and histo-
grams. It can also be useful when generating tracks; however, it reduces the perfor-
mance of the instrument.
The number of considered results can be restricted: "Limit" sets the maximum number
of measurement results per acquisition.

8.2.11.6 Horizontal long-term scaling
In this dialog box, you define the horizontal scale of long-term measurement diagrams.
The length of the long-term measurement is defined by the number of points.
If option R&S RTP-K5 I²S Audio Signals is installed, the trend diagram is configured
here.
