EMC/EMI

Transverse electromagnetic waves are used to transmit the signal between components while PPW waves are used to deliver power to the components. Both waves are useful, but they have to be separated. Yuriy Shlepnev, member of the SIJ Editorial Advisory Board, explains why.

Rohde & Schwarz has added time saving functions to its high end R&S ESW EMI test receiver. It has integrated the fast time domain scan as standard in its R&S ESW EMI test receiver.

 Laird Performance Materials has responded to these challenges by developing Softzorb MCS. This soft, conformable absorber eliminates unwanted signal noise while also acting as a gap filler that reduces coupling—all without damaging sensitive components.

In an analysis of supply chain data and IPC survey results, Zachariah Peterson gives a measured overview of where we are at, and what might happen next.In an analysis of supply chain data and IPC survey results, Zachariah Peterson gives a measured overview of where we are at, and what might happen next.

Benjamin Dannan steps through an in-house process to improve the success rate in EMC compliance testing.

Rohde & Schwarz presents the first turnkey solution for measuring radiated spurious emissions from 5G components in both frequency ranges FR1 and FR2. For this solution the R&S ELEKTRA EMC test software has been upgraded with measurement and calibration routines for 5G.

At EMV 2020 in Cologne, Germany, Rohde & Schwarz will present EMC test solutions specifically for users in the automotive industry: the fastest CISPR-25 certification, a strong and compact BCI test system, and R&S AdVISE version 5, which keeps a close eye even on vibrating display elements during EMS tests.

Low-speed printed circuit board (PCB) designs now have to deal with high-speed switching problems. This article examines the ground bounce generated from an LCD assembly while evaluating the impact of the ground bounce on the system level EMI. Three solution strategies to mitigate the ground bounce are analyzed, the pros and cons of each strategy are provided along with the test results.

Automotive design has captured the public’s imagination, and their expectations are creating countless technical challenges for engineers working in this space. For SI/PI/EMC/EMI engineers, the challenges are unique inside the car due to harsh environments as well as crowded systems.

Here’s a roundup of some of the things taking place at DesignCon 2020.
