The test and measurement methods for "Testing the Immunity to Conducted disturbances induced by an RF Field" are defined by the International standard IEC/EN61000-4-6.
This test can be done by individual components, or by one compact unit like the CIT10 which includes all the necessary components for IEC/EN61000-4-6 testing in one easy to use system.

These types of chambers are utilized for the radiated emissions and immunity testing of electronic equipment and subsystems for commercial, DoD and other related government agencies.
|
|
|
This type of chamber can be certified with the FCC for making an emissions measurement at 3, 5, or 10 meters in accordance with ANSI C63.4 and for immunity compliance testing in accordance with IEC 1000-4-3.
|
|
|
This type of chamber can be certified with the FCC for making emissions measurements at 3 meters in accordance with ANSI C63.4 and for immunity compliance testing in accordance with IEC 1000-4-3.
|
|
|
This type of chamber is designed in conjunction with planar, spherical or cylindrical near-field measurement systems to provide far-field extrapolation of test data taken in the near-field. This approach requires less space than what is typically required for standard far-field environments.
|
|
|
This type of chamber can be utilized as an engineering or pre-compliance chamber for making emissions measurements in accordance with ANSI C63.4 and for immunity compliance testing in accordance with IEC 1000-4-3.

The TDK fully anechoic chamber CAC-S™, with a size of 7.5 m long, 3.0 m wide and 4.0 m high (24'-7" x 13'-1" x 9'-10"), is the most compact anechoic test facility to perform radiated EMC measurements between 26 MHz and 18 GHz. A major advantage of this chamber is that it can be constructed within most industrial buildings and office areas.
The space saving characteristics are obtained by the use of a particular absorber installation technique which was invented and patented by TDK - the double layer technique. TDK ferrite tiles X-131 are mounted onto dielectric panels to cover the complete frequency range from 26 MHz to 1,000 MHz.

Customization
The AEMI chambers have been designed to satisfy most customer's requirements. However, if your testing demands a unique configuration or feature(s) not provided by our standard model, AEMI will work with you to configure a chamber that meets your specific testing needs.
Subsystem Integration
AEMI provides a total turnkey chamber solution including all of the technical expertise, project management, system integration, and installation services that complement the high-quality products we manufacture. This single-source solution ensures completion of a well-controlled, successful project to our customers. AEMI will provide complete antenna measurement system solutions to meet your testing requirements.
Construction
The construction of our anechoic chambers will depend on the shielding requirements of the complete facility AEMI has constructed chambers with stud/drywall methods to welded shielded enclosures, which provide 120 dB of isolation. The most common construction methods are as follows: Standard stud/drywall (no shielding) Stud/drywall utilizing foil (minimal shielding & isolation Welded shielding (120 dB shielding & isolation)

The TA-Series is a standard line of fully-equipped tapered anechoic chambers, delivering high-performance Far-Field antenna testing capability. Ideally suited for performing a variety of measurements, the TA-Series has been specifically developed to meet the increased performance demands of today's wireless and general-purpose antenna measurement applications.
The tapered chamber is a spherical antenna range configured with one side tapering with square-to-round transitions to a true conical section.
The tapering walls bring the reflections into phase coherency so that they are all in phase in the test region, resulting in a smooth amplitude taper illuminating the antenna under test. The energy is transmitted from the conical section toward the terminating end wall absorbers at normal and near normal incidence. Chamber reflections and extraneous energy in the test region are determined primarily by the reflectivity performance of the pyramidal absorber on the end wall. By designing the chamber with high performance terminating wall absorbers, the TA-Series delivers greater accuracy for low frequency measurements (down to 200 MHz).

The 100 to 200 CFM unit is our smallest conditioner and is conveniently designed to run on a 15 amp 115 volt power source. This unit does not require compressed air or ultra pure water (tap water is generally fine). The interior and exterior are constructed of corrosion-resistant stainless steel. Low watt density heaters also contribute to the unit's durability.
