The text indicators are:
RSSI - indicates absolute level of the received radio signal (measured in dBm)
Crosstalk - indicates how much the vertically and horizontally polarized signals
interfere each other (measured in dB)
CINR - indicates the signal quality (for example, how strong is the carrier
signal compared to the noise plus interference level, measured in dB)
Graphical indicator:
The main indicator is the Input Signal stripe.
The height of the Input Signal stripe is measured in dBm by the RSSI scale. The
higher the stripe is, the stronger the signal is.
The stripe may change its position along the Crosstalk scale, showing how much
influence the corresponding device antenna has (for example, how much vertically
and horizontally polarized signals influence each other). The higher the value of
the stripe according to the Crosstalk scale (the farther stripe is from the 0 dB
value), the less influence the antennas have on each other.
Figure 33 - Alignment test - graphical indicator
The top of the Input Signal stripe can be located in black (Good signal) or red (Bad
signal) background areas or somewhere in between them. This means the signal is
good, bad or average correspondingly. When aligning the antenna, it is
recommended to try achieving 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 the packet retries and the percentage of the
total number of transmitted packets.
