Each side of the link (local and remote) has two similar test indicator sets, corresponding to each antenna polarization (one for Vertical polarization and another for Horizontal). This allows controlling the alignment process for each antenna polarization for the local and for the remote device simultaneously.

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).
...
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.
...
Main recommendations when using the “Antenna Alignment" tool:
...
. All described recommendations are applicable to both (Local and Remote) sections.
- The top of an Input Signal stripe should be located in the black area
- Input signals of the two antennas of the device should have similar Cross fading values (Input Signal stripes should be symmetrically to the value of 0 dB).
- Recommended values for RSSI, CINR and Crosstalk are given in the table below.
