4.3.4 Averaged

Data

Averaged Data, that is, a data stream generated by an Averager, is a special kind of triggered
data. Only the last sweep of each averager cycle is added to this data stream. Therefore, a so-
called Avg Trigger is saved together with the Averaged Data stream (not to be confused with the
Averager Trigger that triggers the Averager). This Avg Trigger marks these last sweeps of a cycle.
If you assign averaged data to another instrument, the Analyzer or a display, for example, you
should use the Avg Trigger to trigger this instrument.

Recording averaged data

Together with the averaged data stream, the Avg Trigger is saved in the data file. You need
this trigger when you assign the Averaged Data stream to another instrument, for example
for triggering a Data Display.

Note: If you want to record averaged data

and

triggered data in the same data file, please

make sure that the

Start Time

and

Window Extent

of the

Averager

and the

Recorder

match.

Otherwise, you will not be able to review the Averaged Data stream later.

Replaying (or graphing) averaged data

In the following, it is described how to review an already save averaged data stream with the
Replayer. For more information on how to generate an averaged data stream (either online
during data acquisition or offline with the Replayer), please see chapter "Averager", "Averaging
Data Sweeps".

For replaying recorded Averaged Data streams, click

to add a Data Display to the virtual

rack. Do not use the Averager, which is only used for generating Averaged Data streams!

In the tree view pane of the virtual rack, select the Data Display (here: Display 1), and click the
Data tabbed page. Select the Averaged Data stream (here: Averager 1). You can select the raw
data stream as well, to overlay the averaged data with the raw data, for example.
