Granite River Labs and Rohde & Schwarz extend partnership to broaden European test lab’s compliance testing capabilities

LinkedIn +

Having recently opened its new state-of-the-art high-speed digital compliance test laboratory in Germany, Granite River Labs (GRL) has now further extended its scope of industry services. By adding the R&S ZNB20 vector network analyzer from Rohde & Schwarz to complement the previously acquired R&S RTP164 high-performance oscilloscope, the GRL test lab is now able to offer an even broader range of testing services around established and future high-speed digital technologies like automotive Ethernet or USB.

The R&S ZNB20 provides powerful tools for test fixture characterization and de-embedding. It offers a wide range of measurement results, both in frequency and in time domain, also including transmission line impedance, signal rise time and skew as well as eye diagram and automated mask testing. In combination with the R&S ZNrun compliance automation software, it automates the complete test process from data collection, postprocessing and test report generation.

The R&S RTP is based on a real-time signal processing architecture and provides a powerful tool set for verification and debug, including real-time de-embedding, real-time eye diagram, high-speed serial pattern trigger and protocol decoding, as well as an industry leading jitter and noise separation. Utilizing the R&S ScopeSuite Compliance Test framework the instrument executes automated tests for various high-speed digital interfaces with image-based workflow guidance and a comprehensive test report.

Martin Stumpf, segment manager for digital design test at Rohde & Schwarz, commented, “We are happy to move forward with our partnership with Granite River Labs and equip their new test lab in the heart of Europe. Pairing our expertise in test and measurement with the compliance and certification competency of Granite River Labs will help customers bring their products for current and future high-speed digital communications to market more quickly.”
