Absolute Analysis CPRI Protocol Analyser and Link Valuator

Absolute Analysis’s Investigator for CPRI provides a comprehensive tool set for validating and debugging CPRI links between devices such as remote radio head units and base band units.

General specifications include: supports Protocol Analyzer, Traffic Generator and Performance Statistic; compatible with version 4.2 of the CPRI specification; maximum 6.144 Gbps link speeds; up to 32 time-synchronised ports; lossless 100% line rate data capture; real-time traffic generation of CPRI packets; multiple chassis configurations, including portable, rack mount and ruggedised.

Investigator monitors CPRI link traffic in different modes: Bypass Mode - Investigator connects inline and monitors traffic real time. A maximum 16 full duplex CPRI links can be supported in this mode; Traffic Generation Mode - Investigator is used as an end-point device. A maximum 32 CPRI end points can be supported.

The capacity of Investigator is 16 link pairs. These give the tool the capability of monitoring multiple points simultaneously, and view the results with full time correlation. This capability is not limited to a single protocol. Multiple types of protocols can also be monitored to check data passing through multiple protocol domains.

Investigator captures data at full line rate. Couple this with its advanced triggering and filtering, allowing users to monitor for conditions and errors in real time. This not only saves time to find the problem, but also helps designers quickly find which device is misbehaving. This filtering and triggering is said to be unique and to have the power to reduce debug time by half or more.
