What is EMC (Electromagnetic Compatibility)?
EMC, or Electromagnetic Compatibility, is characterized by the capacity of electronic and communication equipment to function effectively in the presence of interference while also refraining from being a source of interference to neighboring equipment.
EMC = EME + EMI
EME: Electromagnetic Emission (Interference),
EMI: Electromagnetic Immunity.
Effects of EME/EM Interference:
Equipment to Equipment
- Loss of data in digital systems or during data transmission
- Interference with TV and radio reception.
- Malfunction of medical electronic equipment.
- Disruption of automotive microprocessor control systems (e.g., braking) and navigation equipment.
- Malfunction of critical process control functions (e.g., in oil, chemicals, aircraft, railways).
Equipment to Human:
- According to IEEE C95.1 Standard, safety levels are defined concerning human exposure to radiofrequency electromagnetic fields within the range of 3 KHz to 300 GHz.
- ICNIRP Guidelines set limits for exposure to time-varying electric, magnetic, and electromagnetic fields up to 300 GHz.
We focus on the following industries product EMI / EMC testing:
- Industrial Electronics
- Consumer Electronics
- Telecommunications
- Medical

EMI and EMC Simulation and Analysis at the Product Design Phase
During the product design phase, EMI / EMC analysis & simulation are imperative for electronic products intended for commercial, residential, industrial, or military applications. Compliance with EMC (Electromagnetic Compatibility) and EMI(Electromagnetic interference) standards tests are mandatory. These products must operate effectively within their electromagnetic environment and ensure that their functionality does not compromise the performance of other devices. Incorporating EMI / EMC considerations early in the design process is crucial to meet regulatory standards and maintain overall product reliability
How to Avoid Potential Failures
EMI / EMC Pre-Compliance Testing is instrumental in managing common failures encountered during testing by:
- Minimizing RF noise.
- Ensuring cleanliness of power, ground, and static input/output signals.
- Recognizing and monitoring ESD testing locations.
- Calculating ESD levels.
- Selecting and testing the appropriate power adapter.
- Optimizing functional equipment, such as LCDs.
- Inspecting auxiliary equipment for compliance (often overlooked).
- Adhering to the appropriate protection rating.
- Safeguarding sensitive analog and RF circuitry.
In our tech-dependent world, where reliance on gadgets and devices is pervasive, EMC testing has become mandatory to uphold quality standards.
EMC Testing Routine
The EMC testing routine is tailored based on the device under evaluation, its intended application, and the regulatory standards governing its use. The electromagnetic phenomena replicated through EMC testing include:
- Electrostatic discharges associated with static electricity
- Magnetic fields, such as those emanating from electrical wires
- Electromagnetic surges resulting from a lightning strike
- Fast transients caused by electrical switches, relays, motors, and fluorescent lamp ballasts
- Conducted and radiated electromagnetic noise
- Voltage drops due to burnouts or other power interruptions
To simulate these conditions and assess a device’s capabilities, EMC testing labs employ a diverse range of equipment, including surge generators, power amplifiers, spectrum analyzers, and various other testing instruments.
List of EME and EMI Tests
- Radiated Emission
- Conducted Emissions
- Electromagnetic Coupling
- Radiated Immunity
- Conductive Immunity
- Electrostatic Discharge

GigHz Electromagnetic Testing Process
To assess the exposure to electromagnetic fields (EMF), our experts conduct tests on physical quantities such as electric and magnetic field strength, magnetic flux density, power density, and contact current, comparing the results against established reference levels. If the measured quantities exceed these reference levels, a more detailed analysis is conducted to evaluate compliance with basic restrictions for physical quantities, including current density, internal electric field, and specific absorption rate (SAR).
We possess the expertise and equipment to measure:
- Magnetic field
- Electric field
- Electromagnetic field
- Induced current density due to the electric field (EMF for lighting equipment)
- Specific absorption rate (SAR) testing
