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 CFIP vs. RSSI port output voltage (RSSI – Received Signal Strength Indicator). The RSSI
port is located on ODU. The evaluated Rx level has the error +/-2 dB.
