The EN/IEC 61000-4-39 standard describes how Immunity measurements are performed for radiated fields in close proximity.
The exact title of this standard is: "IEC 61000-4-39: Electromagnetic Compatibility (EMC) - Part 4-39: Testing and measurement techniques - Radiated fields in close proximity - Immunity tests"
This review is based on the Edition 1.0 2017-06 version.
In this standard, the description of 'close proximity' refers to a distance between the source and victim equipment of less than or equal to 200 mm for frequencies greater than 26 MHz and 500 mm for frequencies lower than 26 MHz.
The standard describes four different frequency ranges and test methods:
- Magnetic field immunity 9 kHz to 150 kHz - See Application Note 138: "How to perform a magnetic field close proximity test"
- Magnetic field immunity 150 kHz to 26 MHz - See Application Note 139: "How to perform a magnetic field close proximity test using forward power levelling"
- Field generating devices, 26 MHz to 380 MHz - No test method is described
- Field generating devices, 380 MHz to 6 GHz
