Spectrum clearance in mobile networks is becoming ever more important as operators use new bands that previously contained other services. This is particularly important for the 5G NR rollout. 5G NR has already initiated a worldwide deployment of TDD networks in an unknown radio environment where unwanted transmitters can create uplink interference masked by downlink signals, making interference hunting particularly demanding. Automated detection of interference signals before a network switches on can be a big help in addition to traditional manual techniques.

R&S®Server-Based Testing helps reduce test times for workloads that can be parallelized. 5G New Radio (5G NR) multicarrier signals are an ideal workload because each component carrier can be analyzed independently and in parallel. In an example EVM measurement, scenario test times are reduced significantly even when receiving I/Q data from just a single instrument.

Over the past few years, electronics developers have developed a variety of approaches to avoid interference on high-speed signals on printed circuit boards. However, with increasing complexity and frequency, PCBs set new limits, supporting frequencies of 40 GHz and higher. Driven by the fast growing 5G market, today’s digital systems operate in these high frequency ranges that come with completely new challenges. With slope steepness’s of just a few picoseconds, any discontinuity in the impedance and impairment of the inductance or capacitance on the PCB or back drill defects on the PCB can have a massive impact on the signal quality. The industry recognizes that there is a growing need for functional high-speed testing of PCBs. The MicroCraft® E2V6151 series combined with an R&S®ZNB vector signal analyzer delivers a fully automated solution.

With the start and spread of 5G communications services and new form factors such as wearables and foldable phones, an increasing number of flexible printed circuit boards (PCB) that support high frequency signals are being produced. These boards must exhibit excellent frequency characteristics. In the past, a PCB’s frequency characteristics were subjected to sampling inspection using a test coupon. For flexible PCBs, a new method is needed to provide repeatable and proper verification. The Yamaha® MP Series combined with the R&S®ZNBT vector network analyzer measure the high frequency characteristics of a production lot at high speed and high accuracy, enabling 100 % measurement of mass produced rigid and flexible PCBs.

An ever-increasing requirement for data on mobile networks, driven by a myriad of applications from HD video on the move to autonomous vehicles and Industrial IOT, means a part of the new 5G network is to be deployed at mmWave frequencies, with a 26 GHz pioneer band defined for the UK between 24.25 - 27.5 GHz.This near 10-fold increase in frequency over 4G networks opens several challenges, both in the design and implementation of the required sub-components, network infrastructure and end user equipment, and in parallel in the test and measurement approaches used to drive these developments.In this presentation, we will introduce some of the main challenges in test and measurement of a device at these frequencies. We will then present the testing of a 26-28GHz pioneer band dual channel amplifier evaluation module using 5G NR test waveforms.
