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.

Signal Generation and Analysis

This Application Note supplements the video series, describing signal generation and signal analysis for Dynamic Spectrum Sharing (DSS) for LTE and 5G NR. The video series is located below this paragraph.In this illustration, a four frame (40 subframes) long LTE sequence will be created, and exemplary MBSFN slots inserted, carrying 5G payloads. That signal sequence will be compiled and played by the SMW signal generator. The FSW signal analyzer LTE and 5G NR personalities are then used to analyze and verify the content of each subframe/slot.Three methods are presented, (1) Manual Entry using the GUI, (2) SCPI command sequence/remote control and (3) configuration file. The latter variants require the download of various files, available at the bottom.The configuration file approach offers the fastest time to initially setup. The SCPI command sequences provides some insight of the functionality and settings at each step, and the supplied MATLAB® script (only core license required) provides a prototype to illustrate the programming of successive slots or subframes. The Manual Entry approach, using the instrument's front panel GUI, provides a step-by-step set-up instruction, which can itself be augmented with SCPI recording, for easy modification and programming.MATLAB® is a registered trademark of The Mathworks, Inc.

The ‘Data Reduction’ sequence step is an essential part of an EMI Auto Test since it evaluates the relevant frequencies at which the final measurements are to be done. The intention of this application note is to make the data reduction data flow more transparent (contents of input and output tables) and how the parameters (location and relations) influence the evaluation algorithm.

Automated test equipment (ATE) is a cornerstone in production facilities. Devices under test (DUT) have to be measured according to various limits to ensure safe and reliable operation for the user. A production facility must ensure that these tests are performed properly and cover all the necessary test cases. However, the tests must also be executed with sufficient speed. Oscilloscopes (e.g. the MXO series from Rohde & Schwarz) are often a typical part of ATE and can improve the workflow with a dedicated “waiting for trigger” signal.

The effective number of bits (ENOB) is a way of quantifying the quality of an analog to digital conversion. A higher ENOB means that voltage levels recorded in an analog to digital conversion are more accurate. In an oscilloscope the ENOB is not just determined by the quality of the analog to digital converter but by the instrument as a whole. This application note explains how to measure the oscilloscope ENOB and shows results for the R&S®RTO for different settings.

Calibration and Verification Solution

The UWB (Ultra-Wideband) technology is a short range wide-band radio technology specified for device to device communication operating in unlicensed spectrum. It is an RF positioning technology that enables accurate and secure peer-to-peer ranging between mobile devices with robust resistance to interference while consuming very low energy and coexisting well with other radio communication systems. UWB is used for a variety of different applications, such as asset tracking, secure payment, personal tracker, real time location services and keyless access and start of a vehicle etc. According to ABI Research forecasts, there will be well over 1 billion UWB annual device shipments by 2026. Almost every smart phone shipped in 2026 will support UWB services.Talking about testing aspect of a UWB device, in general two test methodologies can be adopted as other wireless products, either the traditional testing mode (so-called conducted test mode) with wired RF connection between the test measurement equipment and device under test (DUT) or over the air (OTA) test mode in an OTA anechoic chamber. Sometimes, it is not always possible or necessary to perform the tests under conducted mode due to the limiting factors, e.g. cost, space, complexity and direct access to the RF connectors of the product. In this case, OTA testing is then becoming a non-evitable approach. Moreover, OTA testing reflects the usage of DUT in a real condition.In this application note, R&S® OTA test solution covering transmitter (Tx), receiver (Rx) and Time of Flight (ToF) testing in Wireless Automated Testing (WMT) environment is described. The measurement results throughout the whole document are based on NXP Trimension™ NCJ29D5 UWB automotive IC.
