IEC 61000-4-45 Conducted Emissions and Immunity Testing
The IEC 61000-4-45 standard is a crucial part of the IEC 61000 series, which addresses electromagnetic compatibility (EMC) for information technology equipment. This particular standard focuses on conducted emissions and immunity testing, ensuring that electronic devices do not interfere with other systems or fail due to external interference.
The tested parameters include both radiated and conducted emissions, as well as the susceptibility of equipment to these emissions. Conducted emissions refer to electrical signals traveling through wires or cables, which can cause interference in nearby circuits or components if not properly managed. Immunity testing ensures that devices are robust against electromagnetic interference (EMI) from external sources.
The standard is especially relevant for semiconductor and microchip manufacturers who need to ensure their products meet international standards before entering the market. It also applies to original equipment manufacturers (OEMs), contract manufacturers, and contract test labs involved in the development or production of electronic devices.
Conducted emissions testing typically involves measuring voltage on a specific frequency band using a spectrum analyzer connected to an antenna. The antenna is placed close enough to the device under test so that it can capture any interference signals that might be emitted. Similarly, conducted immunity tests measure how well a product withstands various types of EMI without malfunctioning.
Signal integrity testing is closely related but focuses more on internal circuit performance rather than external interference. It ensures that data transferred within the device remains accurate and reliable despite potential noise or distortion introduced during transmission.
The importance of conducted emissions and immunity testing cannot be overstated, especially in today’s interconnected world where devices are increasingly dependent on wireless communication technologies like Wi-Fi, Bluetooth, etc., which generate significant levels of electromagnetic interference. Failure to comply with these standards could result not only in product recalls but also costly legal actions due to liability issues.
By adhering strictly to IEC 61000-4-45 guidelines during the design phase and incorporating necessary mitigation measures, manufacturers can significantly reduce their risk of non-compliance later on. This proactive approach ensures that products are not only functional but also reliable, safe, and environmentally friendly.

Applied Standards
The primary standard applicable here is IEC 61000-4-45, which specifies conducted emissions tests and immunity tests for information technology equipment. However, other related standards such as IEC 61000-4-3 (Electrostatic Discharge Immunity) might also be relevant depending on the specific requirements of your product.
It is important to note that while these standards provide comprehensive guidance, they do not replace good engineering practices. Compliance with these standards should always be complemented by thorough design reviews and continuous improvement efforts aimed at minimizing potential sources of interference or susceptibility.
Why Choose This Test?

In addition to these advantages, selecting IEC 61000-4-45 conducted emissions and immunity testing also demonstrates a commitment to excellence in product design and manufacturing processes. This can enhance your brand image among stakeholders and potential customers alike.
Use Cases and Application Examples
| Use Case | Description |
|---|---|
| Data Centers | Data centers house numerous servers, networking equipment, and storage devices. Conducted emissions testing ensures that these components do not interfere with each other or cause disruptions in neighboring facilities. |
| Medical Devices | MEDICAL DEVICES CAN BE VICTIMS OF ELECTROMAGNETIC INTERFERENCE WHICH CAN LEAD TO LIFE-THREATENING ERRORS. TESTING THESE DEVICES FOR CONDUCTED EMISSIONS AND IMMUNITY IS ESSENTIAL TO PROTECT PATIENT SAFETY. |
| Avionics | AIRCRAFT SYSTEMS ARE VULNERABLE TO EMI WHICH CAN CAUSE MALFUNCTION OR FAILURE DURING CRITICAL MISSIONS. CONDUCTED EMISSIONS TESTING HELPS GUARANTEE THAT AVIONICS EQUIPMENT IS ROBUST AGAINST SUCH INTERFERENCE. |
| Automotive Electronics | WITH THE INCREASED USE OF WI-FI AND BLUETOOTH TECHNOLOGIES IN AUTOMOTIVE PRODUCTS, THERE IS AN URGENT NEED TO TEST FOR CONDUCTED EMISSIONS TO AVOID INTERFERE WITH VEHICULAR COMMUNICATION SYSTEMS. |
- Manufacturers of consumer electronics such as smartphones and tablets must ensure their devices comply with these standards to avoid being recalled or facing legal action.
- Medical device manufacturers need to prove that their products are safe from electromagnetic interference, especially in environments where they could affect critical care operations.
- Aerospace companies use conducted emissions testing to verify the integrity of avionics systems during flight. Even minor disruptions can have severe consequences for passenger safety and aircraft performance.
