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

Having recently opened their new state-of-the-art high-speed digital compliance test laboratory in Germany, Granite River Labs (GRL) has now further extended their scope of industry services for a growing European market. 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 Germany test lab is able to offer an even broader range of testing services around established and future high-speed digital technologies like Automotive Ethernet and USB.

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. This step extends GRL Germany’s range of services to VNA-based signal integrity measurements for conformance testing of cable assemblies, connectors and components for Automotive Ethernet, Automotive SerDes Alliance Motion Link, USB, HDMI, and many other standards. 

In addition, GRL provides a broad range of signal integrity measurement and design consulting services including PCB validation and accurate test fixture characterization and de-embedding in high-speed digital and RF applications. The R&S ZNB20 complements the range of offered tests based on the R&S RTP164 high-performance oscilloscope with additional measurements like return loss, differential impedance (TDR), and mode conversion.

Rohde & Schwarz as a leading provider of test and measurement equipment offers state-of-the-art solutions for compliance tests as well as an extensive tool chain for verification and debug tests. Customers seeking official certification by the corresponding standards bodies can use 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.

The R&S ZNB20 provides powerful tools for test fixture characterization and deembedding. 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.

GRL as a leading test services provider for high-speed digital designs and interconnects offers customer services for compliance test and certification as well as design and debugging consultancy. Technologies addressed at its recently-opened lab in Karlsruhe include Automotive Ethernet (including 10BASE-T1S and 2.5/5/10GBASE-T1), USB 2.0 and SuperSpeed USB, USB Power Delivery, Qi wireless charging, as well as HDMI, DisplayPort, MIPI, DDR and others.


Martin Stumpf, segment manager for digital design test at Rohde & Schwarz, says, “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.”

Holger Kunz, President of Worldwide Services for GRL says, “Germany is the leader in innovation in the fields of automotive networking, infotainment, charging, and power management. We are pleased to be moving forward in our partnership with Rohde & Schwarz to ensure a world-class product development ecosystem in Europe. With this relationship, GRL will be able to combine their deep technical expertise with our own extensive capabilities to support the introduction of next-generation products and solutions."

Granite River Labs and Rohde & Schwarz have exhibited their joint competencies in high-speed digital compliance testing at the Automotive Ethernet Congress in Munich from June 1 to 2, 2022 and the MIPI Developers Conference in Munich on June 13, 2022.
