4.8.4.3.2.2 Update
Select this option to update any of the Phy parameters. The Phy parameters are:
Bandwidt
The frequency bandwidth used by the radio. A change in the Bandwidth
parameter will take effect only after resetting the AU/ µBST.
The available options are:
1 – 1.75 MHz
2 – 3.5 MHz
The default is 3.5 MHz.
Downlink (Tx) Frequency
The frequency used in the downlink (from AU/ µBST to SU). The frequency in
the uplink
change in the Downlink (Tx) Frequency parameter will take effect only after
resetting the AU/ µBST.
The resolution is in inc
the radio band of the O

Radio Band
3.5a
3.5b
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 3.5 MHz: 3501.25 to 3598.25.
For a Bandwidth of 1.75 MHz: 3500.375 to 3599.125.
The default is 3551.75 MHz.
