Automated electromagnetic compatibility (EMC) data analysis of an electric drivetrain under real driving conditions is now a possibility with a new solution from AVL and Rohde & Schwarz. It combines the AVL PUMA 2 technology with R&S’s Elektra EMC test software.
“Many customers have been wanting for years to see Rohde & Schwarz EMC analyzers connected to the AVL EMC test automation system. Together, we have finally accomplished this, and are pleased to offer this new solution, improving and accelerating EMC validation of e-drives and vehicles,” said Alban Hemery, department manager for e-motor test systems and EMC applications at AVL List.
Real-time synchronization of measurement data between the EMC testbed, measurement system and automation software is said to be key to efficient and repeatable EMC-compliant component and vehicle development. The solution developed by the two companies supports automated evaluation with simulation of real driving conditions while covering automotive standards.
AVL PUMA 2 automation controls the test run and stores the measured data, in sync with the R&S Elektra which exchanges information between the test unit and the EMC measurement equipment. The Elektra software has been modified to enable automatic and seamless communication with AVL’s Concerto software, replacing a previously manual process. Concerto post-processes the recorded data automatically and gives a full test report against the pre-defined pass and fail criteria.
“As market leader in EMC instrumentation, Rohde & Schwarz has a long and productive history of collaboration with AVL to develop leading-edge test systems for the automotive industry. The enhancement of R&S Elektra to be compatible with AVL’s PUMA 2 is another significant step speeding up EMC test times under real driving conditions, particularly for electric drivetrains,” said Juergen Meyer, VP of the automotive market segment at Rohde & Schwarz.
