The Tx power value sets the transmit power for the highest modulation profile.
In case lower modulation profile(s) has higher max Tx power (based on product’s
specs), the Tx power will be increased automatically without indication in RF
configuration menu.
Mode – operational mode of the link:
o Alignment – Carrier Wave transmission. Used for antenna alignment. No
data over the radio link.
o Static – Fixed modulation profile. If you select Static, you must select from a
list of pre–configured modulation profiles in the Modulation field.
o Adaptive – Adaptive Bandwidth, Code, and Modulation.
The ODU will work on the highest modulation profile based on the CINR
values of the both sides and will present the current modulation profile.
Adaptive mode is the normal and recommended mode of the radio link.
Alignment Status – R/O field, indicating that the ODU is currently in Alignment
mode (by configuration or by inserting DVM probes).
Transmit Asymmetry – Default value is symmetric configuration: 50% for Tx and
Rx (50tx-50rx). For an asymmetric configuration (75%/25% or 90%/10%), Role
has to be set: the Master unit transmits the higher rate (75tx-25rx or 90tx-10rx)
and the Slave unit the lower rate (25tx-75rx or 10tx-90rx).
When selecting asymmetric configuration, Role will be set automatically (refer
to Radio Advanced Settings).
Note that Asymmetric configuration depends on product’s specs and is relevant
only for TDD systems).
Adjust Tx Power so the RSSI at the remote end will not exceed -35dBm (overload
threshold).
When exiting Alignment mode, perform system reset to allow proper operation of
the radio link.
When changing Radio parameters of the link (like Mode, Asymmetry, frequency…)
the link will go down and come up within couple of minutes.
