Powered Device Analyzer 300:


Powered Device Analyzer 300The PowerSync Device Analyzer (PDA-300) is a single-box comprehensive solution for testing IEEE 802.3at PoE Powered Devices (PD’s). It offers one-button, fully automated test sequences and limit processing for critical Powered Device operating parameters. With measurements performed at the Powered Device network interface, many parameters critical to IEEE 802.3at interoperation can be efficiently compared to specification requirements thus fully avoiding the need for extensive interoperability testing with IEEE 802.3at PSE’s and network connections.




The PDA-300 provides defect coverage well in excess of what a commercial PSE or instrument grade DC power supply might offer. It will automatically perform measurements across each powered pair and polarity combination. Measurements such as DC load-over-voltage, classification validity, power on-off thresholds, MPS validity, and detection impedance are readily performed and compared to applicable test limits with no special fixtures or device programming requirements. The PDA-300 can continuously source up to 30 Watts to a PD.


The PDA-300 supports built in automated test sequences that can run from either the instrument front panel or from host PC software (Microsoft Windows) where it will post results to specialized Microsoft Excel reports adding colorful annotation of test limit performance and multi-unit statistics. Tests may be pre-configured for single quadrant (ALT A, MDI) testing or multi-quadrant (ALT A&B, MDI & MDI-X) testing. Test limits can be adjusted in the PDA-300 instrument and/or in the specialized spreadsheet report template. IEEE 802.3at Type-1 and Type-2 PD’s are always subjected to both Type-1 and Type-2 power grants during automated testing to assure interoperability across all PSE types.
