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
o Time Domain Reflectometry (TDR)o Active Link Cable Diagnostics
