This application note contains theoretical background on OTA power and pattern measurements. It gives step-by-step instructions for the verification of the power level and the radiation pattern of a device under test (DUT) in comparison to a golden device, and it presents an approach for verifying the accuracy of beam steering.
What happens when you don’t calibrate?
Keysight’s new book will answer your calibration questions:
- Why calibrate?
- What is measurement uncertainty?
- What’s traceability?
- Does accreditation matter?
- How calibration affects time-to-market or production yield, and more…
Learn the fundamentals of calibration and why it’s so important.
When debugging electromagnetic interference (EMI) problems, design engineers face the challenge of identifying the sources of unwanted emissions early in the design phase. Repetitive testing at the EMC compliance laboratory to identify and resolve these problems is costly and often significantly delays the product launch. Therefore, frequent EMI testing throughout the complete development process reduces the probability of a major redesign, effectively decreasing product launch costs and delays.
Tools that engineers can use for EMI debugging includes oscilloscopes in combination with near-field probe sets. They allow designers to quickly locate and analyze EMI problems early on. High dynamic range and a high input sensitivity ensure that even weak emissions can be analyzed. Fast Fourier transformation (FFT) implementation provides a fast update rate and the persistence display provides insights into the structure of unwanted emissions.

Now that 5G is getting closer to deployment, what are the killer apps going to be that push 5G forward into broad deployment? It is said that 5G could be the next “General Purpose Technology”, but will 5G influential enough to push the technology to the elite status of a GPT? This article aims to explore some of the hottest emerging 5G technology and the potential impact of 5G.
As mobile operators fast-track their 5G deployment plans, chipset and device manufacturers must also accelerate their development activities, including determining how to test 5G data throughput most effectively. Download ‘Testing 5G: Data Throughput’ for more information on how to test high data rates more effectively and some of the available testing solutions, looking specifically at the eMBB use case.
This white paper describes the basic functionality of antennas. Starting with Hertz's Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained.
A more detailed explanation of the functionality of some selected antenna types concludes this white paper.
