Why engineers need IC ESD and TLP data

March 17, 2025 By Jeffrey C. Dunnihoo, Pragma Design Leave a Comment

Design Engineers need ESD and TLP characterization data to make informed decisions to design robust circuits and systems. Engineers often review semiconductor data among several manufacturers when designing a circuit or system. While two or more ICs may perform satisfactorily under normal operating conditions, they may not perform the same under extreme conditions, such as […]

Verify, test, and troubleshoot 5G Wi-Fi FWA gateways

August 21, 2024 By Xiang Li, Keysight Technologies Leave a Comment

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 use remote sensing for DC programmable power supplies

January 15, 2024 By Connor Peck, EA Elektro-Automatic Leave a Comment

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 […]

How to make fast and accurate power-integrity measurements

May 29, 2023 By Joel Woodward, Rohde & Schwarz Leave a Comment

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

May 22, 2023 By Ken Johnson, Teledyne LeCroy Leave a Comment

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, […]
