A new phase noise test instrument covers the frequency range from 1 MHz to 50 GHz with direct down-conversion analog I/Q mixers and baseband signal sampling. The traditional PLL has been replaced by a digital FM demodulator for phase detection and frequency tracking. An additional AM demodulator enables concurrent measurement of phase and amplitude noise. The instrument can measure phase noise as low as -183 dBc/Hz with a 100 MHz carrier frequency and 10 kHz offset within two minutes.

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.

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.

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.
