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.

Watch out for those operating frequencies. Here are some tips to avoid EMC emission test failures.

Return current for a signal always finds a way to flow as close to the signal as possible, thus minimizing the magnetic energy stored in the loop defined by the signal and its return path. So, the return current path is the combination of conduction paths that together minimize the stored magnetic energy. Some elements of the return current path may be part of the design and other elements may be unintentional.

Current density can be an interesting concept. Graphics based on current density can be fascinating. But from a practical standpoint, current density is irrelevant. It is a consequence of other things, not a determinant of them. What follows will explain why.

Here’s what you need to do to enter to win copies of 9 books to round out your SI/PI library—one is out of print and one is hot off the press.

Here are some tips to prepare for a standards audit and avoid being assessed a deficiency.
