The EN/IEC 61000-4-21 standard describes how Immunity, Emission and other measurements are performed in a reverberation chamber.
The exact title of this standard is: "IEC 61000-4-21: Electromagnetic compatibility (EMC) - Part 4-21: Testing and measurement techniques - Reverberation chamber test methods"
This review is based on the 2011 version.
Some random remarks and notes:
- ....
- ...
The field within the chamber is considered uniform if the standard deviation is lower than a predefined value.
| Frequency range | below 100 MHz | 100 - 400 MHz | above 400 MHz |
|---|---|---|---|
| Accepted standard deviation | 4 dB | 3 dB increasing linearly to 4 dB | 3 dB |
The specific measurements are described in several Annexes:
- Annex A:
- Annex B:
- Annex C:
