7.7 Measuring data analysis - zoom and cursor keys
You can select individual measuring data values in measure-
ments with the cursor keys and magnify measuring curves
with the zoom key. This allows you to view measuring ranges
in more detail and analyze them.
Zoom in X-axis
The X-axis is zoomed in with the plus/minus key. The zoom
factor is changed by pressing the key repeatedly. For examp-
le, the displayed spectrum of 0 to 1000 Hz is reduced to a
section of 0 to 200 Hz.
Zoom in Y-axis
The Y-axis is zoomed in with the cursor keys (up, down). The
scaling of the Y-axis is changed. The Up cursor key enlarges
the section, while the Down cursor key reduces it.
Note!
The status line also displays which keys / cursor keys can be
used for zooming in, and which other functions are available
to you (Peak, Harm. Cursor).
Note!
Lines / amplitudes are cut off in the representation if they are
greater than the currently selected range end value. The
numeric display of the frequencies and amplitudes is not
influenced by the representation.
