BSR Physical Sections
The BSR (Base Station Rack) is a complete unit, assembled of three sections: a bottom
section, a middle section, and a top section. The three sections are detailed below.
Base Station Bottom Section
The bottom section of the BSR houses the PAs (power amplifiers), the UPS
(Uninterruptible Power Supply), and the Upconverters.
For a one-sector installation, install the single PA in the PA 3 slot. For a two-sector
installation, install the two PAs in the PA 3 and PA 2 slots.
The test point cluster for the bottom section includes Test Points 1, 2, and 3, which
enable measurement of the output of the Downstream Upconverters pre-PA. A
one-sector installation uses only Test Point 1. A two-sector installation uses Test Points
1 and 2. A three-sector installation uses Test Points 1, 2, and 3.
