Figure 1.32 SP/HP ODU interfaces
UBR flange
Standard UBR flange for ODU interconnection with antenna. Flange size depends on the
frequency used.
RSSI port
RSSI (Received Signal Strength Indicator) port is used to adjust the alignment of antenna for
best performance (for both rough and fine adjustment); this can be done using digital
multimeter which is connected to the RSSI port. The output of the RSSI port is DC voltage and
varies depending on received signal level.
The following chart and table shows typical relationship of the received signal level (Rx level)
displayed by Phoenix G2 vs. RSSI port output voltage. The evaluated Rx level has the error +/-2
dB.
