What is an Ethernet Analyzer?

Troubleshooting tool for Ethernet cables and networks

Short tests vs. Long tests

Range in features

Why an Ethernet Analyzer?

Expanding use of Ethernet technology

Need for a troubleshooting device Faults include:

Cable damage Water ingress Manufacturing Flaws etc…

Design Specifications o Handheldo Color-touch screeno Integrity Checks
