Downlink (Tx) Frequency
The frequency used in the downlink (from AU/µBST to SU). The
frequency in the uplink (SU to AU/µBST) is the Uplink frequency
minus 100 MHz. A change in the Downlink (Tx) Frequency
parameter will take effect only after resetting the AU/µBST.
The resolution is in steps of 0.125 MHz. The available values depend
on the radio band of the ODU and on the Bandwidth, as follows:
Table 4-2: Range for the Downlink (Tx) Frequency Parameter
Radio Band
Bandwidth
3.5a
3.5 MHz
1.75 MHz
3.5b
3.5 MHz
1.75 MHz
NOTE
If the Radio Band is not known (e.g. the ODU is not installed) then the available range
depends only on the Bandwidth, as follows:
For a Bandwidth of 3.5MHz: 3501.25 to 3598.25.
For a Bandwidth of 1.75MHz: 3500.375 to 3599.125.
The default is 3551.75 MHz.
Tx Power
The Tx Power parameter defines the power level of the transmitted
signal at the antenna port of the AU-ODU.
The range is from 13 to 28dBm using a 0.25dBm resolution.
The default is 28 dBm.
