PSE DC Unbalance Tolerance Analysis

Power-over-Ethernet represents a subtle but important impairment to consider in the design and evaluation of PSE switches and midspan PSE's.   Unbalanced splitting of DC current resulting from magnetic imbalances, cabling unbalance, and even RJ-45 connector issues can cause magnetic saturation which in turn distorts and degrades Ethernet signals.   The degree of PSE immunity to DC Unbalance is extremely difficult to characterize.

The PVA-3000 PhyView Analyzer can be combined with the Sifos PowerSync Analyzer (or PowerSync Programmable Load) to perform PSE DC Unbalance immunity measurements with full automation at the single click of a mouse.  The DC Unbalance Test Application is provided as a feature of the PhyView Analyzer Performance Test Suite (PTS).
