Fine align the antenna
There are three methods for antenna alignment. The following table gives comparison:
Method
Features
Using the RSSI test point,
(MAIN Port)
• Preferred method.
• RSSI voltage is updated continuously every 10 ms, regardless of
Operation Mode.
• No need to activate the Antenna Alignment mode if this test point
is used to monitor the receive signal strength.
Using the SPU GUI
• Antenna Alignment mode should be activated. If not, the RSL
value is sent to the SPU every second only.
• RSL message is sent to the SPU every 30 ms.
• RSL updated every 10 ms at the transceiver, regardless of
Operation Mode.
Using the
RFU Control GUI
• When the Antenna Alignment mode is activated, the RSL
message is sent to the SPU every 30 ms.
NOTE
:
For RSSI test point measurement, you will need a digital voltmeter with 3 to 4 digits, 0.3%
DC accuracy, and 0 to 60V range.
