Granite River Labs (GRL) and Rohde & Schwarz are continuing their partnership to build up GRL’s new European test laboratory in Karlsruhe, Germany, opened in December 2021.

GRL has added the R&S ZNB vector network analyser (VNA) 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.

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.

The VNA provides powerful tools for test fixture characteriation 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&SZNrun 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 jitter and noise separation.

Utilising 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 as a leading test house for high-speed digital designs and interconnects 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.
