EMC Consulting Capabilities

The key to EMC compliance is to incorporate EMI control measures in the product initial design. Our consultants work closely with your designers to achieve the simplest, most cost-effective design.

Design Assessment

The “one-size-fits-all” approach does not work in EMI. Our EMC consulting team will identify the specific goals and constraints of your project, and work side-by-side with your designers to assure success.

Requirements Identification

What requirements are applicable? It’s not always clear. We’ll cut through the regulatory and contractual confusion to identify the correct EMI requirements.

EMI Analysis

Newson Consulting uses refined computer analysis techniques and proprietary software and models developed specifically for EMI analysis.

Recommendations

Instructions and recommendations, documented to the level of detail and formality you desire provide a reference for designers throughout the design cycle.

Follow Through

Our responsibility doesn’t end with a set of instructions. We’ll provide assistance, answer questions, review designs, and support developmental and certification testing to ensure success.

Design

Why leave electromagnetic compatibility to chance? Design it in!

Odds are, if your product is not deliberately designed to pass its EMI tests it won’t. We help you optimize your circuits and packaging to avoid costly redesign and retest.

EMC Design

Integrated Approach

Nearly every aspect of electronic design and packaging affects the electromagnetic interference characteristics of the product. At every step of the design, from component selection to system integration, there are opportunities to improve (or degrade) EMI performance. A multi-faceted, multi-discipline approach to EMC design assures the greatest success.

By taking a proactive, preemptive approach, EMI control measures can be integrated into the design. The result is an optimized design that meets its EMI requirements with the lowest cost, lowest expense, and lowest impact on the product design.

EMI Filters

Designing EMI filters that perform as intended isn’t always easy. There are often conflicting electrical and mechanical constraints and frequently the level of filtering required and the optimal filter topology isn’t obvious. As a result, EMI filters are often designed by trial and error and the final design may larger, heavier, and more costly than necessary.

We specialize in custom EMI filter designs for switch mode power supplies, motor controllers, digital processors, power line feeds, power inverters, and signal line drivers and receivers. If you prefer an off-the-shelf EMI filter (which is often an acceptable way to go) we’ll help you select a filter that is appropriate for your application.

Ground System Design

Without a controlled ground system design, electromagnetic interference can be very difficult to control. A carefully designed ground system can do as much to improve EMI as any other aspect of the design.

Our consultants understand the importance of the ground system and can help you structure your ground system for optimal performance or help you operate within the constraints of an existing ground system.

Hardened Circuits

Robust circuit design is fundamental to electromagnetic compatibility. It is almost always more effective to implement EMI controls at the circuit-level than to try to add controls at higher levels, particularly for interface circuits. By controlling waveform spectral content conducted and radiated emissions are minimized, which reduces the need for filter assemblies and shielding.

We’ll work with your designers to help them implement electromagnetically quiet circuit designs that are hardened against radio frequency energy and transients.

Interconnect Cabling

Signal cables and power line cables are the most significant source of radiation from most electronic systems. The way cables are designed and assembled can have a profound effect on the electromagnetic characteristics of the product. Everything from the way shields are terminated to how cables are routed affects electromagnetic interference. We understand these effects will and help you design your cabling for compatible operation.

Electronic Enclosures

The way electronic circuits are packaged affects EMI as much as the electrical characteristics of the circuits. There is more to enclosure design than just shielding effectiveness. Let us show you how to optimize your electronic packaging.

Analysis

We’ll analyze your design using refined computer techniques and proprietary software and models developed specifically for EMI analysis.
