The main item in the graphical indicator is Input Signal stripe.
The height of the Input Signal stripe is measured by Input Signal Level scale in
dB. The higher is the stripe the stronger is the signal.
The stripe can change it location along the Cross Fading scale that shows how
much influence the corresponding device antenna has on the other one, i.e. how
dB. The higher is the stripe the stronger is the signal.
The stripe can change it location along the Cross Fading scale that shows how
much influence the corresponding device antenna has on the other one, i.e. how
much vertically and horizontally polarized signals influence each other. The
higher value has the stripe according to the Cross Fading scale (the farther stripe
higher value has the stripe according to the Cross Fading scale (the farther stripe
is from the 0 dB value) the less influence antennas have on each other.
The top of the Input Signal stripe can be located in black (Good signal) or red
(Bad signal) background areas or somewhere in washed border between them.
(Bad signal) background areas or somewhere in washed border between them.
It means the signal is good, bad or average correspondingly. When aligning the
antenna it is recommended to try to achieve the stripe top to be located in the
antenna it is recommended to try to achieve the stripe top to be located in the
black area.
At the bottom of the Input Signal stripe may appear a special red sub-stripe. This
sub-stripe indicates the presence of packet retries and its percentage of the total
sub-stripe indicates the presence of packet retries and its percentage of the total
transmitted packets number.
The Input Signal stripe may itself change the color indicating the quality of the
received signal (EVM). The possible stripe colors are:
Green – signal quality is good
Yellow – signal quality is worse but acceptable
Red – signal quality is bad.
During alignment test the Input Signal stripe may be moving along Cross Fading
scale and increase or decrease in height indicating the changes in the received
signal. When the top of the stripe is changing its location moving from one point
on the background area to the other it commonly leaves pink and blue marks
that indicate measured maximum and minimum levels of the signal at the
particular point. Thus it makes possible to observe the ―history‖ of the signal
signal. When the top of the stripe is changing its location moving from one point

Main recommendations when using ―Antenna alignment tool‖:
1. It is recommended to start antenna alignment with searching maximum
signal level on a minimal possible bitrate. Afterwards automatic MINT
