Test and measurement specialist Rohde & Schwarz and the University of New Hampshire Interoperability Laboratory (UNH-IOL) extend their ongoing collaboration to expand Ethernet and InfiniBand compliance testing. Both have pooled their expertise to provide methods of implementation (MOI) for precise, fast and error-free compliance testing of high-speed cables and backplanes in line with IEEE 802.3 (up to IEEE 802.3ck) and InfiniBand standards (up to rate designator HDR), using vector network analysis test equipment from Rohde & Schwarz.

To meet consumer demand for ever faster data downloads, from live streaming videos to global videoconferences, Tektronix, Inc. announced three new testing solutions to help drive the future of data transfers.

Rohde & Schwarz continues to expand its range of basic power supplies with the new R&S NGA100 series. The R&S NGA100 is available in four models, providing a choice of single and dual outputs with up to 35 V/6 A per output, or 100 V/2 A per output. Single output models supply up to 40 W, dual output models up to 80 W power. The dual model outputs can be combined to provide up to 200 V or 12 A.

Yokogawa Electric Corporation announced the signing of an agreement with NTT DOCOMO, INC. (DOCOMO) to jointly undertake a proof of concept test (PoC) for the remote control of a plant system by utilizing 5th generation mobile communications (5G), the cloud, AI, and other technologies.

The level of integration of 5G base stations in the FR1 frequency range is increasing, as a new generation of base stations, designated the 1-O type, is becoming more and more common. The 1-O type base stations operate at FR1 frequency range and they have antenna arrays with integrated transceivers, without any access to internal RF ports. This requires all conformance and production testing to be performed over-the-air (OTA). However, OTA testing can be technically challenging.

Keysight Technologies, Inc., a leading technology company that delivers advanced design and validation solutions to help accelerate innovation to connect and secure the world, announced that the company's 5G device test solutions now support 5G protocol conformance test cases for validating location-based services (LBS) mandated by both the Global Certification Forum (GCF) and PTCRB, a certification forum led by representatives from leading U.S. mobile operators.

Anritsu Corporation is pleased to announce that its Radio Communication Test Station MT8000A successfully achieved a downlink (DL) throughput over 7 Gbps using FR1+FR2 Dual Connectivity (DC) technology and 256-QAM modulation in 5G Standalone (SA) mode, in conjunction with MediaTek’s latest M80 5G modem. This industry-first achievement demonstrates Anritsu’s commitment to contribute to the development and wider rollout of new 5G services, which, through its collaboration with MediaTek, verifies leading-edge 5G technology features.

Yokogawa Test & Measurement Corporation announces that it has developed the 760903 current sensor element for use with the company’s world-class power measurement solution, the WT5000 precision power analyzer. The 760903 current sensor element includes a number of new features that simplify the setup and use of external current sensors.

Most of the requirements for higher data rates stem from sensors like cameras around the car, 5G Telematic units (TCUs) and networking backbones for multiple domain controllers. MultiGBASE-T1 Ethernet standard meets these needs by including 2.5G, 5G and 10G speeds. Compared to 1000BASE-T1, MultiGBASE-T1 uses PAM4 (4 levels) modulation with symbol rates of 1.4, 2.8 and 5.6 GHz. The Open Alliance TC15 PMA compliance test specification addressing this standard is still in a draft state.

Keysight Technologies, Inc., a leading technology company that delivers advanced design and validation solutions to help accelerate innovation to connect and secure the world, participated in a first PCI Express® (PCIe®) 5.0 Preliminary FYI Workshop sponsored by PCI-SIG®, with solutions that simulate, characterize and validate PCIe 5.0 devices enabling Keysight to drive consistency in test standards that will advance innovation in hyperscale data centers, 5G and cloud computing.
