Figures
Deals with measurements to be carried out during factory acceptance tests and type approval tests on a complete simulated digital radio relay system, following tests on the individual parts of the system. Coverage includes Bit Error Ratio (BER), Jitter, and Verification of Protection Switching Operation. Also includes detailed diagrams.
