With continuously increasing data rates, signal integrity in high speed digital designs becomes more and more demanding

English - 8 Jul 2022

Vector Network Analyzers (VNA) are gaining popularity in the Signal Integrity community as time domain measurement and analysis tools. VNAs with 8 ports or more can provide significant decreases in test time by migrating from a 4-port measurement system to an 8-port measurement system. For tight tolerance DUTs that are barely within the test limit lines, small increases in accuracy can be realized by testing all of the test parameters at once, because the entire test setup is at the same temperature. This application note discusses the thermal advantages of testing an 8-port DUT with the R&S ZNBT VNA. The use of the ZNBT to assess and debug two differential pairs in a 20-inch backplane is presented.

This application note reviews a new calibration subsystem which consists of Inline Calibration Units (ICUs). These ICUs are designed for in situ use, so they are left in place both during the calibration procedure and during the measurement of the Device Under Test (DUT).This adds versatility, convenience and accuracy to the VNA based measurement system, as it means the calibration can be refreshed at any time without manually disconnecting the DUT from the test system.

Small cell is a compact base station with smaller form factor and lower transmission power in comparison to the conventional macro base station. It covers relatively small area and serves less users. Usually, small cell can be integrated into the existing mobile network. By the evolution of radio access technology, the role of small cell has been changing through the evolution path. In the 2G/3G time, its role was to provide coverage in corner cases. Later during LTE, networks are not just providing coverage but capacity too. Small cells were then used to provide the addition capacity where required without adding additional spectrum. Now in 5G era, network operators use densification as an important strategy to provide seamless 5G services which demand coverage, capacity and performance too. With use cases requiring the 5G millimeter wave (mmW) rollouts, it makes sense to use small cells for densification due to the propagation characteristics of mmW.In this application note, we will shed light on the testing aspects of a small cell throughout the product life cycle with particular focus on the production test solution for the small cell device under test (DUT) in FR2 (frequency range 2, mmW frequency band) in Over the Air (OTA) environment for option 6 split based on radio communication tester R&S®CMP200 and OTA chamber R&S®CMQ200. The document is complemented with more insights into test solutions used in typical R&D test applications towards the second half of the application note.

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.

Designing and implementing an active phased array antenna requires precise characterization of individual components and the integrated performance of the array. To ensure an accurate test of the intended adaptive nature of the active phased array antenna, the embedded algorithms need to be tested as well.This application note aims to explain test procedures and give recommendations towards characterization of the relevant parameters for active phased array antennas and their passive subsystem, as often used in applications for Mobile Communication and RADAR. This application note describes transmit signal quality testing, multi-element amplitude and phase measurement techniques both in receive and transmit cases and introduces a new automated test methodology antenna radiation pattern measurement over frequency. This paper also describes the test system used for transmit and receive module (TRM) characterization in active array antennas.

5G networks will need to offer more capacity and flexibility while lowering the operational expenses of the system. Two new technologies can simultaneously address both the increase in capacity and the increase in energy efficiency: Virtualization & Massive MIMO. This white paper provides an overview of test solutions addressing current and future requirements for antenna verification including both conducted and over-the-air (OTA) test methods, which result from applying Massive MIMO antenna technology.This white papers complements the white paper (1MA276) from Rohde & Schwarz, which introduces fundamental theory behind beamforming antennas and provides calculation methods for radiation patterns, a number of simulation results as well as some real world measurement results for small linear arrays.
