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.

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.

Rohde & Schwarz launched the R&S ZNA, the world’s first purely touch-operated vector network analyzer, originally two years ago. The newly introduced models cover frequency ranges of up to 50 GHz and 67 GHz.

Raydiall Automotive have been developing, together with their Japanese partner Yazaki, various automotive ethernet components for the link segment (communication channel) section...

Rohde & Schwarz announces new functionalities to its Advanced Voice Quality Assurance system (R&S AVQA), extending the functionality from IP to radio frequency (RF). This takes the advantage of the ED-137 protocol with information such as Frequency ID or Radio Signal Strength Indicator (RSSI). With this information, AVQA provides great new insights into the RF channel.

In order to realize industry 4.0 use cases such as mobile robots or automated guided vehicles, industrial network deployments must guarantee very high availability, reliability, and in many cases low latency communications. 5G NR technology including its latest enhancements specified in 3GPP Release 16 enables ultra-reliable low latency communications (URLLC), ideal for private campus network deployments. However, as with any wireless system, the communication link is subject to potential interference on the deployed spectrum bands.

Rohde & Schwarz has announced details of an upcoming Oscilloscope Days seminar event for 2021, a valuable opportunity for electrical engineers to learn the essentials of oscilloscopes by joining virtual hands-on sessions that relate to real world design challenges. The free to attend live training webcast will take place on May 18 and 19, 2021.

Rohde & Schwarz, a global leader in broadcast media technologies has announced the introduction of a new member of its SpycerNode media storage family. Completely Ethernet based, the R&S®SpycerNode SC targets the storage requirements of both broadcast and post production workflows. SpycerNode SC is designed to fulfil the requirements of modern post production teams, where performance is a higher priority than redundancy, but reliability, compact design and affordability are key requirements.

The flexibility of automotive Ethernet makes the simple twisted-pair network technology ideal for an ever-increasing range of in-vehicle networks. In order to verify, commission and troubleshoot designs based on an automotive Ethernet communication link, it is important to have an instrument that is capable of not only measuring and verifying compliance to the standards but also decoding the messages and reliably triggering on them.

With two new source measure units (SMU), Rohde & Schwarz enters a market previously not addressed by the power products of the test and measurement specialist. The performance of the new R&S NGU201 and R&S NGU401 SMUs enables simultaneous sourcing and measuring of currents and voltages with high precision.
