Granite River Labs and Rohde & Schwarz Extend Partnership on European Test Lab’s Capabilities



Granite River Labs (GRL), a global leader in compliance test and certification of high speed digital designs, cables and connectors, and Rohde & Schwarz continue their partnership to build up GRL’s new European test laboratory in Karlsruhe, Germany, opened in December 2021. GRL has added the R&S ZNB20 vector network analyzer (VNA) from Rohde & Schwarz to the test equipment resources of their test lab. With this step, the lab’s range of industry services is being extended to VNA-based measurements for verification, debugging and compliance tests of cable assemblies and connectors for Automotive Ethernet, Automotive SerDes Alliance, USB, HDMI and many other standards. Besides that, GRL can provide customer services for accurate test fixture characterization and de-embedding in high speed digital and RF applications. Last but not least, the R&S ZNB20 also complements the range of offered interface tests based on the R&S RTP164 high performance oscilloscope with additional tests like return loss and mode conversion measurements as required in host/interface testing.

Rohde & Schwarz as a leading provider of test and measurement equipment offers state-of-the-art solutions for compliance test as well as an extensive tool chain for verification and debug test. Customers seeking official certification by the corresponding standards bodies can use the the same Rohde & Schwarz test solutions in-house for R&D and pre-compliance testing, before getting their products officially verified and certified by GRL.
