How to accurately measure noiseand ripple on microcontroller power supply circuits?

Wed, 04 Feb 2026 11:53:12 +0200

Power in an integrated circuit design is a tightly controlled commodity. As the affordable microcontroller market has exploded, there have been increasing demands on power distribution networks, resulting in lower supply voltages. Lowering the supply voltages helps to reduce power consumption. Many designs today have 3,3 V, 1,8 V and even a 1,1 V supply, and as those supplies have become smaller, so have the tolerances on those supplies. Tolerances have dropped from 10% to “1% - 5%”.

You must scrutinize DC power rails and voltage lines for quality and integrity. Ripple, noise and transients are riding on those voltage rails, and before you can reduce them, you need to measure them. The goal is to make sure that the power rail is clean. Fundamentally, you need to measure ever smaller and faster AC signals riding on top of the DC ones.

Using the Keysight N7020A power rail probe and the 14-bit Keysight HD3 Series oscilloscope makes it easier to find and analyze the AC signals of your DC power supply that you were unable to see before. Check below application note „5 Tips for Measuring Ripple and Noise“ how to test power rails in your design as accurately as possible.

Mon, 15 Dec 2025 06:31:07 +0200

New generation of FieldFox handheld analyzers delivers all-in-one capability for spectrum monitoring, signal analysis and generation, interference hunting, and cable and antenna testing in both field and lab environments.

Key capabilities of the N99xxD-Series FieldFox
handheld analyzer include:

120-MHz IQ streaming with built-in SFP+ high-speed data interfaces for 10 GbE data transfer, ensuring uninterrupted data capture and efficient streaming
Wideband signal analysis and playback for advanced troubleshooting in complex RF environments, spectrum utilization monitoring, and interference detection
Seamless field-to-lab workflow, enabling re-creation of real-world signal scenarios for in-depth lab analysis and system optimization
Unmatched RF performance, delivering absolute amplitude accuracy of ±0.1 dB —without warm-up — surpassing most handheld and benchtop analyzers currently in the market

Today’s radio frequency (RF) environments are becoming increasingly complex and dynamic, as mission-critical, commercial, and consumer systems converge across the spectrum. From 5G and radar to emerging 6G and satellite communications, engineers face mounting challenges in identifying interference, capturing transient events, and characterizing wideband signals without data loss. Traditional handheld analyzers often fall short — limited by bandwidth, streaming speed, or data-transfer bottlenecks.

The new FieldFox D-Series bridges this gap by combining the ruggedness of a field instrument with the power and precision of a lab analyzer. It empowers users to capture, stream, and replay every signal event, enabling faster troubleshooting, deeper analysis, and greater confidence that no data is missed, even in the most complex RF landscapes.

The N99xxD-Series includes 14 models (combo or spectrum analyzers) to cover the maximum frequency of 14, 18, 26.5, 32, 44, 50, and 54 GHz. Each model supports more than 25 software-defined FieldFox applications, including vector network analysis, spectrum and real-time spectrum analysis, noise figure measurement, electromagnetic interference analysis, pulse signal generation, and direction-finding using techniques like angle of arrival (AoA) and time difference of arrival (TDoA). A Linux-based operating system further enhances the analyzer’s security and file management, while a touchscreen interface improves usability, efficiency, and reduces errors.

Keysight has introduced advanced artificial intelligence (AI) capabilities to its FieldFox handheld analyzers and Keysight Spectrum Management Software (KSMS S9910A), delivering faster and smarter spectrum operations. By leveraging wideband signal capture and the new machine learning model (S9916A), the solution now classifies major wireless standards — including LTE, 5G NR, Wi-Fi, and Bluetooth — with exceptional speed and accuracy. This integration automatically and dramatically reduces time-to-resolution and provides deep insights into congested or contested spectrum environments, empowering customers to make informed decisions in real time.
