Granite River Labs and Rohde & Schwarz extend partnership to expand compliance testing capabilities of European test lab – rAVe [PUBS]

With the R&S ZNB20, GRL can offer VNA-based measurements in its test laboratory in Germany.

Granite River Labs (GRL) recently opened its new state-of-the-art, high-speed digital compliance testing lab in Germany and has now further expanded its range of industrial services to a growing European market. By adding the R&S ZNB20 vector network analyzer from Rohde & Schwarz to the previously acquired R&S RTP164 high-performance oscilloscope, the GRL test lab can offer an even broader range of test services for established and future high-speed digital technologies such as automotive Ethernet or USB.

Granite River Labs (GRL), a global leader in conformance testing and certification of high-speed digital designs, cables and connectors, and Rohde & Schwarz continue their partnership to establish GRL’s new European test lab in Karlsruhe, Germany, which will 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 expands the lab’s industrial service offering to include VNA-based measurements for verification, troubleshooting, and conformance testing of cable assemblies and connectors for Automotive Ethernet, Automotive SerDes Alliance, USB, HDMI, and many other standards. In addition, 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 supplements the range of interface tests based on the R&S RTP164 high-performance oscilloscope with additional tests such as return loss and mode conversion measurements, as required for host/interface tests.

As a leading provider of test and measurement equipment, Rohde & Schwarz 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 from the relevant standards bodies can use the same Rohde & Schwarz test solutions internally for R&D and pre-compliance testing before having their products officially verified and certified by GRL.

The R&S ZNB20 offers powerful tools for characterization and deembedding of test adapters. It offers a wide range of measurement results, both in the frequency and time domains, 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 entire test process from data acquisition and post-processing to the creation of test reports. The R&S RTP is based on a real-time signal processing architecture and offers a powerful toolset for verification and debugging, including real-time de-embedding, real-time eye diagram, high-speed serial pattern trigger and protocol decoding as industry-leading jitter and noise separation. Using the R&S ScopeSuite compliance test framework, the device performs automated tests for various high-speed digital interfaces with image-based workflow guidance and a comprehensive test report.

As a premier test house for high-speed digital design and interconnect, Granite River Labs provides customer services for conformance testing, certification, and debugging consulting. Technologies addressed at the recently opened Karlsruhe location include Automotive Ethernet (up to 1000BASE-T1 and 2.5G/5G/10GBASE-T1) and USB 2.0 and USB 3.2 as well as HDMI, DisplayPort, MIPI, DDR and others .

Martin Stumpf, Segment Manager for Digital Design Test at Rohde & Schwarz, says: “We are excited to continue our partnership with Granite River Labs and outfit their new testing lab in the heart of Europe. Combining our test and measurement expertise with Granite River Labs’ compliance and certification expertise will help customers bring their products to market faster for current and future high-speed digital communications.”

Holger Kunz, President of Worldwide Services at GRL, says: “Germany is the innovation leader in the areas of automotive networking, infotainment, charging and power management. We are excited to advance our partnership with Rohde & Schwarz to ensure a world-class product development ecosystem in Europe. With this relationship, GRL will be able to combine its deep technical expertise with our own extensive capabilities to support the launch of next-generation products and solutions.”

Granite River Labs and Rohde & Schwarz showcased their combined capabilities in high-speed digital conformance testing at the Automotive Ethernet Congress from November 1st to 15th.
