3.
Set the D/L and U/L output power levels in the corresponding fields:
●
The maximum power level can be set individually for uplink and downlink of each channel.
●
The level can be set in 1 dBm steps from maximum power “Max” to maximum power minus
9 dBm “Max-9”.
●
The Max. power level depends on the number of chains used (decreases with each
additional chain).
●
The power level can also be set to OFF, meaning that no output power is transmitted out in
the chain.
Output power level
Note!
Verify that the power levels for the inactive chains are set to
OFF
.
The current value can be read in the top part of this screen (36 dBm in example below).

(depends on no. of chains used)
4.
In Config field, select Low Delay or High Selectivity for the U/L and D/L frequencies.
5.
In the Downlink:
Verify that the Return Loss is approximately 10dB, indicating the antenna is installed
correctly. (The Return Loss measures the reflected signal on the Server Antenna port of the
repeater. If the value is approximately 3dB, either the port is open or check the antenna
installation.).
Set attenuation to maximum value.
Note!
The values shown in the figure below are for example only.
Config field
U/L Attenuation D/L Attenuation
Lower the Attenuation level step by step until the desired output power level is reached. In
this e30 dBm. (Zero attenuation = maximum gain).
