What's New

At the International Microwave Symposium IMS 2025 in San Francisco, Rohde & Schwarz will highlight its newest test instrument that will enable RF engineers to discover signals once out of reach.

Since the discovery of electromagnetic interference (EMI) in the early 1900s, the need for testing for radiated emissions continues to grow as products get more complicated. The time to test has also grown, and, in some cases, can take days to complete. The introduction of fast Fourier transform (FFT) technology into EMI receivers can greatly decrease the required testing time, but is it applicable for everyone?

Achieving a balance between effective cyber protection and free trade can present multiple challenges. In this article, we outline recent and upcoming cybersecurity protections that are being enacted in the U.S., Canada, the European Union (EU), and other jurisdictions.

The European Union’s 2024 Cyber Resilience Act makes complying with the cybersecurity standards in the Radio Equipment Directive (RED) mandatory. Your firmware developers may need a significant amount of time to implement the provisions, so if you have not already started securing your product to the new regulation, you need to do so now.

This is the first of seven articles devoted to the topic of shielding to prevent electromagnetic wave radiation. The results presented here are valid under the assumption of a uniform plane wave with normal (perpendicular) incidence on a boundary between two media.

A new version of Technical Report TR18.0-01-25 (TR18) on ESD Electronic Design Automation (EDA) Checks by the ESD Association’s Working Group 18 is about to be released. This article, divided into Part 1 and Part 2, provides guidelines for the EDA industry and the ESD design community for establishing a comprehensive ESD verification flow to address the ESD design challenges of modern ICs.

This white paper is a technical overview of reverberation chamber design for EMC radiated immunity testing. It covers mode density, tuner efficiency, chamber Q, and validation methods in accordance with IEC, MIL-STD, and RTCA guidelines.

Siglent's RF signal generation capabilities extend into complex IQ signals with wide bandwidth and fast symbol rates. Learn more about the capabilities and functions of RF signal generators, including the newest SSG6082A-V 8 GHz Vector Signal Generator.

Commercial EMI testing requires strict pass/fail criteria with no allowances for upset. Military/aerospace susceptibility testing uses higher levels but allows more flexibility - equipment may be acceptable despite susceptibility at specific frequencies if those frequencies won't be encountered operationally, prioritizing practical deployment considerations.

The U.S. Federal Communications Commission (FCC) has adopted new spectrum rules that will expand the use of frequency spectrum currently reserved for fixed and mobile services.
