Configuring RF Parameters and Channels
The gain range is up to 85dB for
all bands
and is set by default to its maximum value of
85dB.
NOTE: The gain will then be modified automatically to its optimum value by the SALC mechanism.
This mechanism performs gradual learning of traffic load characteristics and adjusts the Repeater RF
Gain accordingly. (See section 1.4 for more information on the SALC mechanism).
The following filter selection options are available:
NOTE: The available filter selection options can be viewed in the Band Info tab (section 5.2.2).
•
Narrowband filters:
12.5 to 1,000 kHz (in 12.5KHz steps)
•
Wideband filters:
200 to 20,000KHz (in 200KHz steps)
•
5MHz filters:
5,000KHz
4.2.1 Control Params Tab
You can define up to 12 filters according to their bandwidth, power, gain and gain-delta
(used for noise control). The defined filters are graphically displayed in the lower part of
the screen.
To configure the signal level and channels
1. In the topology tree, click
Root
and then
700/800
.
2. Click the
Control&Params
tab. The displayed window is divided into two main
areas:
•
System – overall parameters for the
selected service.
•
Sub-band (filter) definitions – used to define up to 12 sub-bands and their RF
parameters.
•
Sub-bands view – graphical display of defined sub-bands for the service.
