PVA-3000 PhyView Analyzer

The PVA-3000 PhyView Analyzer is designed to bridge the wide coverage gap between comprehensive Ethernet twisted pair PHY compliance testing and rudimentary link verification testing. The PVA-3000 introduces an innovative multi-port capability dedicated to 10/100/1000BaseT physical layer characterization under controlled impairments including line loss, ingress noise, jittered or offset timing, and even Power-over-Ethernet.

Key features of the PVA-3000 include:

  • Faster and More Informative Alternative to Packet Testing
    • Answer “What’s Wrong, How Wrong, and Where?”
  • No Scopes, Fixtures, Probes, Generators, Test Modes, or Cable Spools!
    • Test  Any LAN Interface, Anywhere
  • Innovative New Measurements on Transmitted Signals
  • Versatile Programmable Impairments for LAN Receiver Testing
  • Single Connection Receiver Testing or Dual Connection Packet Loss

  • PVA Interactive Graphical User Interface Software for Interactive Testing

  • PowerShell PSA Software for Automated Script Developement and Debug

PHY Performance Test Suite

Ethernet interface testing has never been easier than the PhyView Test Suite for the PVA-3000. This group of fully automated tests can be automatically sequenced across up to 24 10/100/1000BaseT ports to produce colorful and graphical reports of DUT PHY performance.   Sequencing and reporting is accomplished with just a few mouse clicks in PVA Interactive software or with a single command in PowerShell PSA. Unlike rudimentary link testing, PhyView Performance Tests clearly and independently characterize transmitter, receiver, and physical interface performance in quantitative terms that predict link performance over the full range of possible applications.

  • Automatically Examine All PHY Performance Margins 
    • Transmitter Signal Integrity
    • Receiver Performance Under Stress
    • Physical Interface Characteristics 
  • Automatically Sequence Up to 24 DUT Ports per PVA-3000 Chassis 
    • That's 96 Gigabit Pairs and 48 10Base-T/100Base-TX Pairs! 
  • Full Support On Compact PVA-3002

PSE DC Unbalance 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 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).
