Optimizing the RX section
RX (Main) Optimization/ATP
To test the RX Main antenna system follow the instructions in Table K-2
and refer to illustration Figure K-1(3-sector configuration).
Table K-2: Optimizing the RX (Main) section of the Companion Frame
 Step Action
1 Connect the RX test cables to the antenna ports 1A-3A (for 3-sector optimization) or
antenna ports 1A-6A (for 6-sector optimization).
2 Login the LMF and select MPC (see Figure K-2 for display screen and field location).
3 Run the RX tests.
RX (Diversity) Optimization/ATP (Single Frame)
To test the RX Diversity antenna system follow the instructions in
Table K-3.
Table K-3: Optimizing the RX (Diversity) on a Single Frame
 Step Action
1 Connect the RX test cables to the expansion ports on the I/O plates labeled 1B-3B (for
3-sector optimization) or expansion ports 1B-6B (for 6-sector optimization).
2 Login the LMF under EMPC (see Figure K-2 for display screen and field location).
3 Run the RX tests.
RX (Diversity) Optimization/ATP (Two Frame)
To test the RX Diversity antenna configuration on a two frame
Companion BTS system follow the instructions in Table K-4.
Table K-4: Optimizing the RX (Diversity) on a Two Frame Companion Site
 Step Action
1 Connect RX expansion cables from the expansion ports on the other Companion frame
labeled 1A-3A (for 3-sector optimization) or expansion ports 1A-6A (for 6-sector
optimization) to the 1B-3B (for 3-sector optimization) or expansion ports 1B-6B (for
6-sector optimization) see Figure K-1 for an illustration of the configuration.
NOTE
Connect the cables from the 2nd frame A ports to the B ports of the 1st frame.
2 Login using the LMF select MPC (see Figure K-2 for field location on LMF display screen)
NOTE
- Although the test will be done to one frame, the RX cable will be connected to the
other frame’s corresponding antenna ports.
- The other frame has to be powered up and include all the RX Path Components.
