Step 2: Interpret the Spectra Displays
There are up to four displays labelled A, B, (C & D for quad unit) which shows the spectra
being received on the two (or four) diversity antennas of the NETNode you are attached to.
But, there could be several NETNodes transmitting on the mesh thus it is necessary to
define which unit we are looking at.
This is done with the option buttons on the left side of the spectra display. In our example,
the option button for Mast is selected. This means the two displays are showing spectra for
that NETNode’s transmissions as received on our node’s two antennas.
Step 3: Interpret the Interference Display
The last option button is called Interference. When you select this, the displays show the
spectra when none of the NETNodes in the mesh are transmitting. This enables us to look
for interference on the frequency we are planning to use for our mesh.
