EMC performance in the proximity of RF transmitters

We hereby announce that we can test according to the IEC 61000-4-39 standard in the frequency range from 9 kHz to 26 MHz and from 380 MHz to 6 GHz. We have successfully passed the requirements for accreditation by the Slovenian accreditation for the IEC 61000-4-39. 

Nowadays, the variety and dimensions of intentional transmitters are becoming more and more extensive. Intentional transmitters can be used for radio communication, induction cooking devices, RFID registration, electronic article surveillance systems, tracking devices, wireless charging systems for electric vehicles, and much more.

Each intentional transmitter transmits a relatively high amount of energy in a narrow frequency band. If equipment contains electronic components and circuitry that are sensitive to electromagnetic fields from these intentional sources, and degradation of the equipment could result in a risk, it is advisable to consider this in the design phase of the equipment and take preventive measures to avoid possible future issues. When portable devices are involved or installed in proximity to the intentional transmitter, the potential risk of device malfunction or even safety risk becomes even more important.

For the known reasons, IEC 61000-4-39 standard has been developed to consider electromagnetic fields in the vicinity of equipment with specific methods.

We hereby announce that we can test according to IEC 61000-4-39 standard in the frequency range from 9 kHz to 26 MHz and from 380 MHz to 6 GHz.

The illumination windows are:

• 10 cm x 10 cm for the frequency range from 9 kHz to 150 kHz,
• 8 cm x 8 cm for the frequency range from 150 kHz to 26 MHz,
• 10 cm x 10 cm for the frequency range from 380 MHz to 6 GHz.

Nowadays, only the latest medical standard IEC 60601-1-2:2014 + A1:2020 introduces testing at specific frequencies in the low-frequency range. Future product and safety product standards are likely to introduce similar tests due to the known risks.
