4.7.4 Antenna Selection (Si CPE)
This option enables selection of either an internal antenna, an external (detached)
antenna or automatic antenna selection.
The available options are 1 to 6 (Internal), 7 (External), or 8 (Automatic).
The default is internal antenna 3 (opposite to the connectors' side).
The numbering plan of the internal antennas is described in the following figure:
4.7.5 Frequency Scanning Parameters
The Frequency Scanning menu enables viewing and updating the set of
frequencies to be used during the scanning process. The Frequency Scanning
parameters are Start Rx Frequency, End Rx Frequency, Scanning Main Step and
Intermediate Steps. The set of frequencies to be scanned is defined as follows:
The “main” frequencies are defined by the Start Frequency and Main Step, using
the formula F(N) =Start Frequency + N*Main Step;
F(0) = Start Frequency,
NOTE
Some frequencies are available only with a certain Bandwidth. For example, in 3.5 GHz units that
support bandwidth options of either 1.75 MHz or 3.5 MHz, the frequencies 3400.375-3401.125,
3498.375-3499.125 are available only with bandwidth of 1.75 MHz. Prior to selecting any of these
frequencies the Bandwidth must be configured to 1.75 MHz.
