Comparing Reverberation Chamber Standards: SAE J1113/27, GM 9120P, etc.

[Mr Jake]

Hi, does anyone know anything about reverberation chambers?
specifically does anyone know about the industry standards, a camparason between
SAE J1113/27
GM 9120P
GM 3100GS
GM 9114P
or any other standards which allow for a 2 -> 3Ghz operation would be helpful,
thanks

Take a look at Lindgren's chamber literature, or even give them a call. They can probably point you in some directions. Also, a search of the current SAE standards should be helpful, as 9120P and 9114P may not be updated as much as J1113/27. Its been a few years, since I was active in EMC.

There is quite a bit of info on IEEEExplore, wherein you can access the abstracts as a non-member, as well as googles scholar. The biggest issue with mfgr specific standards, and to some extent the SAE ones, is they often times bow to convenience, rather than to real world user needs.

Reverberation chambers are a type of electromagnetic compatibility (EMC) testing equipment used to test electronic devices for their immunity to external interference. There are several industry standards that govern the operation and performance of reverberation chambers, including SAE J1113/27, GM 9120P, GM 3100GS, and GM 9114P. These standards outline the specific requirements and procedures for testing devices in a reverberation chamber, such as the frequency range, power levels, and measurement techniques.

SAE J1113/27 is a standard developed by the Society of Automotive Engineers (SAE) specifically for the automotive industry. It covers the frequency range of 2-18 GHz and specifies the methods for measuring radiated emissions and immunity in a reverberation chamber. This standard is widely used in the automotive industry for EMC testing of vehicles and their components.

GM 9120P is a standard developed by General Motors (GM) for the testing of electronic components and systems in vehicles. It covers the frequency range of 2-18 GHz and outlines the procedures for testing radiated emissions and immunity in a reverberation chamber. This standard is also used in the automotive industry, particularly for testing GM vehicles and their components.

GM 3100GS is another standard developed by GM, but it covers a lower frequency range of 400 MHz to 8 GHz. It specifies the test procedures for measuring radiated emissions and immunity in a reverberation chamber for electronic components and systems used in GM vehicles.

GM 9114P is a standard developed by GM for the testing of radiated emissions and immunity in the frequency range of 400 MHz to 10 GHz. It is used for testing electronic components and systems in GM vehicles.

It is important for companies to comply with these standards to ensure the quality and reliability of their products. These standards provide a common framework for testing and comparison of results, allowing for consistent and accurate measurements across different testing facilities.

In terms of a comparison between these standards, they all cover similar frequency ranges and have similar procedures for testing radiated emissions and immunity in a reverberation chamber. However, there may be slight variations in specific requirements and measurement techniques, so it is important to consult the specific standard being used for testing.

In conclusion, reverberation chambers are an important tool for EMC testing and the industry standards, such as SAE J1113/27 and GM 9120P, provide a framework for
