We take a unique approach

Advanced Solutions

The solution to an EMC issue requires a mix of good electronic knowledge, RF understanding, PCB layout skills, and electronic design skills. Our team combines the best talent in EMC and electronic design in the UK to achieve this. It is with great pride that we can say that we have never failed a project up to this point.

Design review

Design reviews should be part of any company's process. By conducting a design review, you may save your company months of development and testing, as well as increase the chances of passing EMC on the first attempt.

EMC troubleshooting

Identifying the cause of an EMC issue can be time-consuming, and it can delay you from getting your product on the market for a very long time before you figure it out. You can find out more about this service by clicking here.

EMC Training

EMC training is one of the services we offer. Click here for more information if you are interested in designing electronics that will pass EMC.

EMC precompliance

There are two levels of pre-compliance that we offer.

Level A, which is done in-house using the equipment we have available.

Level A+, done with the help of one of our EMC lab partners here in Cambridge.

Why Moving the EUT Changes the Emissions Plot

1. Introduction – why a small change can make great differences in the plot Did this happen to you. You go to the testing lab. you do a full RE scan and the scan looks great. Then you Rotate the EUT 90° Lift a cable Move the EUT by 20 cm Change cable routing And the emissions plot changes. This is not randomness. It is physics. Radiated EMC measurements are strongly influenced by how the product couples to its environment. I want to discuss this today, so, next time, when you

Power Supply Emissions: How I Separate Differential Mode from Common Mode

When I debug EMC problems on a DC/DC converter, I use a very simple test to understand whether the dominant mechanism is Differential Mode (DM) or Common Mode (CM) . The test is simple: I increase the load and observe what happens to the emissions. If: The peak frequencies stay the same, But the amplitude increases with load, then the behaviour is consistent with differential-mode emissions . This is aligned with what TI explains in their EMI material: Differential-mode nois

Identifying Low di/dt and High di/dt Currents in DC‑DC Converters

Introduction In switch‑mode DC‑DC converters, not all currents are equal from an EMC, signal integrity, or reliability perspective. A critical distinction must be made between low di/dt current paths and high di/dt current paths . Misidentifying these paths is one of the most common root causes of excessive EMI, poor efficiency, unstable switching behaviour, and failed compliance tests. This article focuses on: How to correctly identify high di/dt and low di/dt current loops

How Parasitic Capacitance Breaks Optocoupler Isolation in Switching Power Supplies

Optocouplers are widely used in isolated power supplies to transfer feedback information across an isolation barrier. In schematics, they appear as a clean and robust solution: no galvanic connection, clear separation between primary and secondary, and good noise immunity. In practice, optocouplers are often one of the main entry points for switching noise into the control loop. They are commoinly used in isulated AC/DC, DC/DC and PoE applications. This article explains why
