Manufacturing

Specification Conformance

Verify that a PD conforms to 802.3at or 802.3bt standards to assure interoperability.

Conformance to IEEE 802.3at or 802.3bt standards is necessary to assure PD interoperability  with all PSE’s in all connection environments while also assuring safe and reliable operation.  PD designers are challenged by the complexity of IEEE PoE standards and by the fact that PD controller components, by themselves, do not assure a conforming powered device. 

Product Recommendation
  • Fully automated, one-click, plug'n play testing of all critical PD conformance parameters
  • Comprehensive and clear reporting of specification parameters and statistics
  • Test suite for 802.3at, Type-1 and Type-2 PD's supported on both PDA-602 and PDA-604 platforms
  • Test suite for 802.3bt Type-3 and Type-4 PD's supported on PDA-604 platform
  • Robust coverage including all aspects of PD power demotion and LLDP power negotiation
  • Powerful Load Monitor for real time power draw specification compliance testing including average, peak, and Tcut window violation checks

PoE LLDP Emulation

Verify that a PD properly negotiates power and operates within LLDP negotiated power budgets.

If your PD utilizes Link Layer Discover Protocol to negotiate power with a PSE, testing for compliance to the LLDP portion of the 802.3at or 802.3bt standard will be just as important as any other aspect of conformance testing.   All 802.3at Type-2 and 802.3bt Class 4-8 PD’s are required by their respective standard to support PoE LLDP power negotiation.

Product Recommendation
  • Flexibly emulate Type-2, Type-3, and Type-4 PSE's that utilize LLDP for power management
  • Assess protocol and message timing conformance to 802.3at and 802.3bt standards
  • Control basic protocol parameters including PSE type, capabilities, and TTL
  • Colorful spreadsheet reporting of protocol and timing violations
  • Utilize LLDP to negotiate and validate power draw compliance during the PD Conformance Test Suite and with the Load Monitor

Physical Layer Integrity

Asses LAN Physical Layer Integrity at the PD while powered by a PSE.

Much like PSE ports, PD 10/100/1000Base-T interfaces must function in all connection environments with DC power sharing the same wires.  

Product Recommendation
  • Automated, one-click analysis of PoE induced signal impairments via mechanism of DC current unbalance.
  • Measure transmitted SNR and low frequency power spectral distortion
  • Assess receiver performance with physical impairments including worst case insertion loss and ingress noise
  • Utilize with passive power injector that can furnish either 2-pair or 4-pair power to PD

Manufacturing

Avoid quality issues in the field by automating acceptance tests for PDs.

As a hardware intensive feature of any powered device, PoE powering is vulnerable to component and process defects that can lead to safety and interoperability problems in the field.  Highly automated PD power testing can increase confidence in the integrity of every device shipped.

Product Recommendation
  • Intuitive, high level, interpreted scripting language
  • Standard feature of all PDA-600 instruments
  • Extensively documented with built-in command help
  • API access to work in the programming language of your choice
