Signal Integrity, Power Integrity, & EMC Blog 

The constant development of new and emerging technologies, such as Artificial Intelligence (AI), electric vehicles, and 5G/6G communication systems, are driving higher board densities than ever before. This has led to the popularity of Voltage Regulator Modules (VRMs) as a way to help alleviate space in the PCB design. Depending on the power requirements of an application, power supplies can consume a significant amount of real estate on a PCB design to achieve a stable and l

If you're looking to select a power supply to use in your design, read this before dropping it or a VRM into your schematic.

This article provides an in-depth exploration of how to effectively capture large signal behaviors through sequential trigger measurements.

Are traditional anechoic chambers necessary for testing applications, or can RF EMI tents suffice? Let's see where tent tech is at.

Zone triggering with the MXO5 oscilloscope allows intuitive, versatile trigger conditions for multiple non-synchronized signals.

The goal of this article is to show design and test engineers the process of how to accurately measure the impedance of any VRM.

This Is What Saving $6000 Looks Like Introduction: When it comes to electronic test instruments, oscilloscopes are the Swiss Army knives of the lab. They can replace digital multimeters, spectrum analyzers, and more. But what happens when your trusty oscilloscope faces a voltage surge or transient? That’s where our hero—the Picotest Port Saver™ DC Block—comes into play as a protective component designed to safeguard your oscilloscope. Why do Oscilloscopes Need Protection? Os

Learn about how both the ESRP3 and the ESRP7 are engineered to be reliable partners in pre-compliance testing and diagnostics.

The Bode 500 VNA has a dynamic range exceeding 120 dB, ensuring accurate vector network analysis, and frequency response measurements.

By Benjamin Dannan and Steven Sandler, Picotest.com Introduction and Application Optocouplers and optoisolators are very common semiconductor devices that allow an electrical signal to be transmitted between two isolated circuits. These devices are used to provide essential input/output isolation for protection and safety between a safe and a potentially hazardous or electrically noisy environment [1]. Some typical applications for optocouplers include microprocessor input/ou

Benjamin Dannan and Steve Sandler Part 2 of 3 This article is the second part of a 3-part series: Part 1 - How Much CMRR is Needed? Part 3 - The Measurement Result with another VNA Measuring the Known DUT Let’s continue our discussion from where we left off in our last blog (link). If you recall, after we defined how much CMRR is required to measure a 40 µΩ (2000 Amp) PDN with a 2-port probe, we said we would show you how to make a 40 µΩ impedance measurement with the 2-po

In this blog, we will examine the noise performance of various probing solutions with a Rohde & Schwarz (R&S) MXO 5 oscilloscope.
