Radio and EMC Testing Considerations
Understanding radio compliance and electromagnetic compatibility (EMC) issues to help ensure that products meet regulatory testing requirements and customer expectations.
Basic Parameters of the Normalized Site Attenuation (NSA) Method for Open Area Test Sites (OATS) and Semi Anechoic Chambers (SAC) in CISPR 16‑1‑4
This article discusses the requirements for the qualification of an Open Area Test Site or Semi Anechoic Chamber for measuring radiated disturbances from 30 MHz to 1 GHz.
Defining Product Grounding in the Automotive EMC Test Plan
This article presents the importance of defining product case and load simulator grounding in an automotive EMC test plan.
EMC Testing… The EU Experience
Changes to the FCC compliance rules in the U.S. now enable manufacturers to save time and cost by allowing self-testing. This article outlines some of the basic factors that determine RF and EMC behavior and how these determine compliance test methods.
Selecting the Proper RF Amplifier for the Required Field Strength
More power costs more money when it comes to broadband power amplifiers, so we typically only specify/buy to meet our current needs rather than what we may need in the future.
Qualification of Interface IP for Charge Device Model Based on Peak Current
The voltage based CDM classification has practically no meaning for IP qualification. In this article, we propose an alternative CDM qualification, which is based on a peak current criterion.
Let’s Talk About Unconventional EMC Chambers
In this article we will address less mainstream, non-typical EMC test chambers that are often used in automotive, military, and other pre-compliance types of test environments.
HBM Pin Combinations
Should I use the pin combinations in Table 2A or Table 2B per Human Body Model (HBM) standard JS-001?
Lossy Material Quiets Leaky Air Vents
This article presents the results of experiments to measure the effectiveness of lossy material in reducing RF emissions from perforated air vents such as those commonly used on computer enclosures. The results show good performance compared to those with conventional metal vents.
Let’s Talk About Real-time Spectrum Analyzers
Many real-time spectrum analyzer solution providers provide in-one-instrument add-ons which allow users to perform both the traditional swept-mode measurements in addition to real-time measurements.
