Surface scope
The surface scope presents data from all segments
inside a surface scope. Thus, it functions as an
intermediate total, simply to gain overview of the
different surfaces and provide easier analysis of the
source under test.
Scope view
Presents a graphical view of the measurement surface.
The A-weighted value for the surface is displayed,
along with A-weighted data for each individual
segment. Select the displayed function using the
FUNC
key. Scope view is illustrated in Figure 21.58.
A red frame will be present around a segment in scope
view if engineering mode is selected, and only a single
scan is performed. In survey grade, only a single scan
is required. A green frame indicates that the required
number of scans has been performed for the segment.
Simple view
A graph is presented for sound pressure along with
either sound intensity or sound power. Warnings are
indicated for each frequency band, and the complete
surface. Toggle between sound power and sound
intensity using the
FUNC
key. Press
INFO
to bring up
the warning window. In surface scope, the warnings
are summed and they display how many warnings
there are for all segments inside the surface. The
display is equal to simple view for a segment.
Advanced view
Two different graphs are presented by toggling the
FUNC
key. The warning window is available for all
graphs by pressing the
INFO
button.
The first graph shows sound power, sound intensity
and sound pressure at the same time, the same way
as for a segment.
