InfiNet Wireless R5000 Technical User Manual

―Start Test‖/‖Stop Test‖ buttons at the bottom of the page start/stop the

alignment test.

―Exit Test‖ button returns to the ―Device Status‖ page.

―Help‖ button displays help guidelines for antenna alignment.

Once the test is started antenna alignment can be monitored using graphical and

text indicators. Indicators for both local and remote devices are displayed

together on the same page that allows viewing the alignment process for both

sides of the link.

Each side of the link (local and remote) has two similar test indicator sets

corresponding to two antenna polarizations (rx chains) of the device (one for

Vertical polarization and another for Horizontal). This allows controlling the

alignment process for each antenna polarizations for local and remote devices

simultaneously.

Text indicators are the following:

 Input Level, dBm – RSSI indicator of the input signal. Measured in dBm.

 Error Vector Magnitude (EVM) – indicator of the measured input signal

quality. It should be as high as possible. The recommended level is not

less than 21.

 Chain 0 Signal Level – input signal level indicator of antenna number 0

(vertical polarization).

 Chain 1 Signal Level – input signal level indicator of antenna number 1

(horizontal polarization).

 Retries – percentage of transmit packet retries.

Graphical indicator:

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

much vertically and horizontally polarized signals influence each other. The

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.
