Universal Test Setup for PD / Load
Data and Power Conformance Tests (Basic Streaming Version)

Download App Note

Telebyte’s Ethernet-APL Universal Test Setup (Basic Streaming version) supports PD / Load with one setup for Ethernet-APL Conformance and Interoperability Data and Power testing. The PSE may be emulated as a golden reference link partner device. The small footprint saves valuable laboratory test space while the fully automated approach saves time and money and provides repeatable test results. The solution is easy to use, allowing tests to be performed by technicians with minimal training. There is no need to plug/unplug different instruments and fixtures in the test setup. Additional features include automated software for controlling DUTs and all test equipment. The software generates Pass / Fail Reports for Ethernet-APL Conformance Power and Data tests. The basic streaming version uses a customer’s PC with a serial or network connection to transfer data to the PC for post processing the captured Ethernet signal with Telebyte’s probes and Test Automation Software.

Customers may purchase all integrated test setup instruments from Telebyte.

An optional Switch Matrix is also available to automate the switching in of multiple DUTs in a test bed to the Telebyte Universal Test Setup.
