Performance of ADI Wireless BMS Ensured Using Rohde & Schwarz Record and Playback Solution

Case Study Overview

Analog Devices (ADI) faced the challenge of creating a realistic test environment to investigate electromagnetic interference (EMI) in their wireless battery management systems (W-BMS) for electric vehicles. Traditional drive tests are costly, time-consuming, and difficult to replicate, especially when it comes to capturing critical corner cases. ADI needed a more efficient solution to ensure their W-BMS performed reliably in real-world conditions.

To meet this need, ADI leveraged Rohde & Schwarz's RF spectrum record and playback solution, which includes the R&S®FSW signal and spectrum analyzer, the R&S®SMW200A vector signal generator, and the R&S®IQW wideband I/Q data recorder. This setup enabled ADI to accurately recreate complex RF environments in the lab, ensuring consistent and reproducible testing. As a result, they gained higher confidence in their product’s real-world performance while also reducing costs by minimizing the number of necessary drive tests.
