8.4.4 Exporting Data

The data of the record being viewed can be exported for further display or processing. Depending on
the type of record two formats can be chosen from:
•
If the record contains raw signals, the data can be exported to either .wav or tab-delimited text
format. The .wav format is preferred when dealing with a large quantity of data because it
provides a smaller, more efficient storage. When exporting as .wav a separate file is created
for every axis present in the record.
•
If the record contains raw signals, the data can also be exported to a tab-delimited text format
that can be easily opened by spreadsheet applications such as Excel. In that case the user
should be mindful of the quantity of points contained in the record. The text formatting can
easily produce files of huge sizes.
•
If the record contains RMS levels or signal statistics the data can only be exported to a tab-
delimited text format.

8.4.5 Graph Controls

All graphs can be adjusted using the following techniques:
8.4.5.1 Zoom Controls
To the left of each graph is a two-button control. The left-most looks like a magnifying glass. It is used to
zoom-in and zoom-out the corresponding graph. To use it, simply press the button, and choose one of
the following zoom functions:
•
Zoom X-Y
•
Zoom X
•
Zoom Y
•
Zoom-Extents
After choosing the function, the cursor changes to a magnifying glass. Click and drag on the graph to
apply the required zoom.
Keep in mind that each graph has a separate zoom and pan function. Select the proper function for the
particular graph you are interested in before applying it. Make sure that the cursor changes to the
proper function when the mouse is hovered on top of the graph.
Note that all three graphs are always synchronized along the X scale. Whatever zoom is applied to the
X-scale over one graph is always applied to the other two. This way the X-scale is always the same for
the three graphs.
8.4.5.2 Pan Controls
To pan a graph left, right up or down, first press on the Hand button to the left of the particular graph
you are interested in. Then position the mouse over the graph. Left-click to "grab" the graph, and move
the mouse to pan the graph as desired.
