Automated Ethernet-APL Power & Data Conformance Testing
(Budget for PSE/Power Switch)
Telebyte’s Ethernet-APL Universal Test Setup supports PSE Source with one setup for Ethernet-APL Conformance and Interoperability Data and Power testing. 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. A customer’s PC with a serial and network connection is used to transfer data to the PC for post processing the captured Ethernet signal with Telebyte’s Test Automation Software. Customers may purchase all integrated test setup instruments from Telebyte. Please note this same setup can be used for testing PD Loads. An optional switch matrix is available for switching in of multiple DUTs in a test bed.
