This document describes the Integris 2000 product, which is a test instrument for validating CPRI serial communications used in radio access network installations. It can test aspects of the physical layer such as optical power and bit errors, and validate the CPRI layer state. Specific tests described include CPRI link testing, cable testing, and SFP module testing. The Integris 2000 also has unique polling functions that allow it to retrieve inventory and configuration information directly from remote radio units without a baseband unit. It features a rugged laptop form factor for use in the field and allows remote control and viewing of tests as well as automatic report generation in PDF format.
