• The Spectrum Graph readout will be empty.

2. Choose a range for the frequency band that must be scanned for

interference or excessive radio noise by doing either of the

following:

• Set the start and stop frequency selection to the system

defaults (4 950 MHz to 5 825 MHz) by clicking

the Default button.

• Enter custom start frequency and stop frequency values for

the frequency band that must be scanned for interference,

in the Start Frequency (MHz) and Stop Frequency (MHz)

fields.

3. In the Commands table, click the Start button.

• When the frequency scan is complete, the Spectrum Graph

window will show the scan result.

• Signal quality for each channel is shown as a function of

signal noise quantity (in decibel-milliwatts) at each

frequency. The higher the value shown on the graph, the

poorer the signal quality. A green display indicates high

signal quality. Yellow indicates falling quality. If the signal

display is red, there is excessive signal noise.

IMPORTANT

If you are scanning a network with overlapping

communication channels, the number of

detected Fluidmesh units may be larger than

the actual number of deployed units.

4. To view a specific part of the graph, roll the mouse wheel forward

to zoom into the window, then click-and-drag the window left or

right.

5. To reset the window to default size, click the Reset Zoom button

on the upper right-hand corner of the Spectrum Graph window.
