By Xiang Li, Keysight Technologies Follow these three steps to ensure your fixed-wireless access designs will be compatible with the Wi-Fi fronthaul and 5G backhaul. Many areas lack the wired infrastructure to bring residential broadband access. Making those connections has become costly and inefficient. Fixed Wireless Access (FWA) has emerged as a compelling alternative to […]

How to build and manage a top-notch test team
Test engineering requires more than technical skills to build a successful team and complete projects on time and within budget.
How to use remote sensing for DC programmable power supplies
In this FAQ, you’ll learn how to know if your test application needs sensing and how to properly wire a power supply to a load. Calibrating certain sensing circuits, such as those used in electric vehicles (EVs), is critical to get right. An inaccurate calibration of an automotive battery monitoring circuit could, for example, allow […]
The factors of accurate measurements
All measurements need reliable, accurate equipment that’s traceable to worldwide standards. Without that, measurements have no value. From ensuring product quality in a factory to safety to letting every individual use a computer or phone, accurate measurements are critical in every aspect of our lives. In the automotive industry, accurate measurements of components and the […]
Automate double-pulse testing in WBG devices
By automating double-pulse testing of wide bandgap devices such as SiC and GaN power devices, you can cut setup and analysis time. The need to reduce carbon emissions drives investments in electrical technologies, particularly in data centers and electric vehicles. In its most recent Elective Vehicle Outlook report, Bloomberg estimates a 27% increase in global […]
How to make fast and accurate power-integrity measurements
Today’s electronic devices with fast FPGAs, ASICs, and other ICs rely on ever-smaller power rail voltages with tight tolerances. Engineers who incorporate these ICs into their systems need to use oscilloscopes, probes, and measurement techniques that align with today’s tight voltage rail tolerances. Making an accurate ripple measurement with an oscilloscope on a 1 V […]
Measurements verify power integrity
Engineers should measure and analyze power integrity on the power and ground planes of a board’s power distribution network. Understanding power integrity is crucial when evaluating circuit power quality because it has a direct influence on performance. Power integrity is a subset of signal integrity, whose assessment ensures that signals have suitable amplitude, rise time, […]
5G mmWave test builds on RF best practices
The high level of integration in today’s mmWave phone means traditional test methods no longer apply.
What are the critical measurements in satellite uplinks and downlinks?
Noise measurement, LO substitution, receiver stress testing, power measurement, CCDF and PAPR characterization, and antenna-pattern measurement play critical roles in link budget, bit-error rate, and SNR requirements.
How modularity benefits test systems
By understanding the key issues at every phase of the product lifecycle, engineers can make decisions that result in flexible, reliable, and scalable test systems. Taking a modular approach to test system development can accelerate development and mitigate risk throughout the entire product lifecycle. When it comes to designing and building automated test systems, today’s […]
