PIM Test DXB0372 Emirates Park Hotel Analysis and summery

- The process of testing start with Initial Full Sector test to determine the root cause of the PIM, For the site DXB0372,there are 3 sector altogether, we found several faulty Hybrid Coupler, faulty connections and jumps. The process of correction started with changing faulty component, and move on gradually to combiner testing, and diplexer testing, and so on till All DAS testing.

- The process of testing each sector involves numerous, and continuous testing, and retesting, of all sector stages. At this stage we will provide as much details as possible for all testing screen shots, we will make sure to confirm in clear screen shots successful pass of each sector components.
