2. What is an Ethernet Analyzer?  Troubleshooting tool for Ethernet cables and networks  Short tests vs. Long tests  Range in features

3. Why an Ethernet Analyzer?  Expanding use of Ethernet technology  Need for a troubleshooting device Faults include:  Cable damage  Water ingress  Manufacturing Flaws  etc…

4. Design Specifications o Handheld o Color-touch screen o Integrity Checks o Time Domain Reflectometry (TDR) o Active Link Cable Diagnostics (ALCD) o Digital Spectrum Analyzer (DSA) o PoE Power Source Device Detect o 3-source power o Battery o Power-over-Ethernet o DC input o Active and Passive Mode

5. Conceptual Design  Time Domain Reflectometry (TDR) Catch reflections off discontinuities-> location and impedance

6. Conceptual Design Active Link Cable Diagnostics (ALCD) Passive Signal Processing->accurate cable length

7. Conceptual Design  Digital Spectrum Analyzer (DSA) Discrete Fourier Transform-> frequency spectrum
