Granite River Labs (GRL), a test house for high-speed digital designs and interconnects, 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. GRL can also provide customer services for accurate test fixture characterization and de-embedding in high-speed digital and radio frequency (RF) applications. 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, a 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 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 de-embedding. It offers a wide range of measurement results, both in frequency and in time domain, 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 compliance test framework the instrument executes automated tests for various high-speed digital interfaces with image-based workflow guidance and a comprehensive test report.
Granite River Labs offers customer services for compliance test and certification as well as debugging consultancy. Technologies, addressed at its recently opened location in Karlsruhe 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.
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.
