  • Sifos 提供以太网物理层测试方案 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 simple packet 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. The PVA-3000 tests Ethernet switches and routers, discrete LAN interfaces, link transmission components, and network service integrity at any 10/100/1000Base-T interface.

    PVA Interactive Graphical User Interface Software

    Get productive quickly with the PhyView Analyzer using PVA Interactive software (for Microsoft Windows). Configure test ports, configure impairments, control link-up conditions, and assess link stability with simple menu selections. Meters such as Rx Power, SNR, Power Spectral Distortion, Wideband Return Loss, and Wideband Crosstalk are readily configured to produce single or multi-pair information in a single mouse click. Full access to the PhyView Performance Test Suite with one-button test sequencing is supported under the automated test menu. MAC packet definition and transmission as well as packet counting are supported along with fully automated, one-button test port calibration sequences.
