VeriPhy and PoE Quick Tests
QA and Manufacturing test scripts included standard with PhyView Analyzer, PowerSync Analyzer, and PowerSync Programmable Load solutions
PVA-VeriPhy Automated Multi-Port 10/100/1000BASE-T Qualification Script
The PVA-3102 PhyView Analyzer includes a flexible and fully automated test application for evaluating 1 to 6 10/100/1000BASE-T ports at a time with a test throughput of as little as 75 seconds per port tested! Accessible from PowerShell PSA, the pva_veriphy program offers effortless defect coverage of transmitters and receivers and is readily sequenced to test groups of 4 or 6 ports per test cycle.
PoE Multi-Port High Throughput PSE Verification
The PSA-3000 PowerSync Analyzer includes a sample PSE automated test script, psa_quick_test, that recovers critical PoE parameters from PSE test ports with an effective test throughput of less than 15 seconds per tested port. This application can be used to rapidly qualify PSE functional performance.
The PSL-3000 and PSL-3024 PowerSync Programmable Load include a sample PSE automated test script, psl_quick_test, that recovers critical PoE parameters from PSE test ports with an effective test throughput of less than 30 seconds per tested port. This script can be used as is, or with user modifications, to rapidly qualify PSE functional performance. |

DC Unbalance Tolerance in PSE's
The PoE Impairment Challenge
Much like cable attenuation, alien crosstalk, and impedance mismatches present physical layer impairments to packet traffic on 10/100/1000BASE-T links, Power-over-Ethernet (PoE) also has the potential to present significant impairment. Unlike other forms of link impairment however, the assessment of PoE effects on link integrity is extremely challenging to characterize. Furthermore, the mechanisms for PoE impairment involve the combination of disparate components including Power Sourcing Equipment (PSE's), Powered Devices (PD's), cabling, and connectors.
Automated DC Unbalance Analysis from Sifos
Available as part of the PVA-3000 PhyView Analyzer PHY Performance Test Suite, Sifos offers a highly unique, fully automated, plug-and-play approach to DC Unbalance tolerance analysis on a PoE port. This solution combines one or more PVA-3000 test ports with PowerSync Analyzer or PowerSync Programmable Load (PSA/PSL) test ports and a PVA-DCU DC Unbalance Unit to assess physical layer signaling response to a range of precisely controlled DC Unbalance conditions. |

Powered Device LLDP Analyzer
The IEEE 802.3at (PoE+) standard requires that all "Type-2"
(>13Watt) Powered Devices support the new PoE LLDP protocol. This protocol allows PSE's and Powered Devices (PD) to communicate power requirements and power allocations with 0.1 watt granularity. It also allows for in-service adjustments to power allocations.
Unlike traditional LLDP (Layer 2) protocol, PoE LLDP involves messaging "hand-shakes" and includes protocol timing requirements. Hence, PD testing requires flexible PSE-side protocol emulation. Ideally, this testing is combined with actual power monitoring functionality as can be provided by the Sifos PDA-300 Load Monitor.
Sifos PDA-LLDP serves as a flexible, configurable emulator of PSE LLDP protocols with full ability to process PD requests and provide user-specified power allocations. Key features include:
- PD verification to IEEE 802.3 Clauses 33 and 79
- Flexible PSE LLDP Modeling and Configuration
- One-Button LLDP Protocol Capture and Analysis
- Flexible Emulation of 802.3at Type-2 LLDP PSE's when combined with a Sifos PDA-300
- Compact, Portable 2-Port Emulation
- Overcomes Coverage Limitations of End-Span & Mid-Span PSE's
- PSA Interactive Graphical User Interface
- PowerShell PSA Automation Scripting
- Pop-Up Excel Spreadsheet Protocol Trace Reports
