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.

High-speed serial interfaces often transmit data with differential signaling. For probing on the signal, trace differential probes are used. Besides the differential inputs, these probes often provide an additional connection for ground – especially the higher bandwidth models. The ground connection on the R&S®RT‑ZMxx modular multimode probes can be used to improve measurements on high-speed differential interfaces.

Reflection measurements are a common way of assessing antenna system performance. When a minimum amount of the transmitted signal is reflected, it indicates that the transmission energy can reach the intended coverage. Undesired high reflection causes the system to be inefficient and can damage components. Reflection measurements can be expressed in terms of return loss, VSWR and reflection coefficient.

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.

Timing components such as low jitter oscillators and clocks are necessary to facilitate increasing data rates in high speed digital designs. As part of the overall system design, the components also have to perform in the system’s non-ideal power integrity environment and limit the power supply induced phase noise and jitter from power rail disturbances. Measuring the power supply noise rejection (PSNR) requires accurate generation and leveling of artificial, sinusoidal disturbances and measurement of resulting phase-noise and jitter impairments.
