EMC Debugging and Analysis

EMC or EMI problems are often encountered during the final stage of product development stage, which is during the certification stage. The EMC engineers always have to troubleshoot and solve the EMC problem empirically which take a lot of time and effort.

EMC Debugging and Analysis


The basics of ensuring the product to pass EMC certification test is to precisely control and mitigate the interference between electronic devices or components.

We are experienced in both EMC measurement and simulation, which gives us insight to the right cause and implement correct mitigation technique.

Besides, we can also provide early stage evaluation service to reduce the prototype revisions.

EMC Debugging and Analysis

Our Services include: Conducted Emission/Immunity

It is very likely you are experiencing difficulty in passing certain SI test, or there are some concerns that the current prototype may not pass certification test. Fret not, we use cutting edge simulation tool to perform realistic SI simulation based on signal type or speed. This gives us better insight on where to improve on the PCB routing.

We can also include physical constraints such as connectors into the PCB to simulate the PCB in 3D. This gives us more information as the connectors could be the limiting factor which distort the signal integrity.


Radiated Emission/ Immunity

Radiated emission and immunity troubleshooting is one of the most complicated task, because the Equipment Under Test (EUT) must be in operation mode, where all components are running simultaneously. This makes troubleshooting difficult because isolating the source is almost impossible.

By combining both measurement and simulation approaches together, we are able to identity and mitigate the source faster.

Radiated Emission

Electrostatic Discharge (ESD)

With the help of simulation tool, we are able to identify the ESD propagation path and also estimate the level of induced voltage and current. This is almost impossible for actual measurement, where it only provides pass/fail condition.


Frequently Asked Questions

What is EMC testing?

Electromagnetic compatibility (EMC) testing measures the ability of devices, equipment, or systems to function normally in their electromagnetic environment, without introducing intolerable disturbance or be disturbed by neighbouring devices or systems.

What services are included in the EMC debugging and analysis?

Depending on the scope, we are able to use simulation and measurement troubleshooting method to isolate the root cause. This method is more effective and cost-efficient. We are able to help in all radiated and conducted emission and immunity, including ESD.

How do you solve EMC problem?

We use both simulation and measurement to identify the source and perform design changes or design improvement. We will then verify the changes and provide a design change report.

How much do you charge for EMC debugging and analysis?

Depending on the scope, the charges depend on the man-day and measurement services included. We are very transparent on the charges. Please contact us to find out more.
