Our baseline semi-anechoic 3-meter chambers are designed to provide an optimal environment for radiated emissions and radiated immunity measurements.
|ANSI C63.4||Radiated Emissions|
|CISPR 11, 12, 16, 22, 25, 32||Radiated Emissions|
|IEC 61000-4-3||Radiated Immunity|
TDK’s standard configuration targets +/-3.5dB NSA and +5.5dB sVSWR performance. Our NSA, sVSWR, and Field Uniformity measurement results will provide unmatched reliability, repeatability, and the highest performance environment possible.
|Minimum Internal Working Space||8.50 m
|RF Shielding Inner Dimensions||9.00 m
|External Dimensions with support steel||9.30 m
1)This design assumes a 30cm (12”) raised ground plane floor inside the chamber for ease of cable management and installation of a flush mounted turntable.
2)The interior height is designed to accommodate known current boresight antenna mast designs. Be sure to check the height requirements since the space necessary can vary significantly from supplier to supplier of boresight antenna masts.
With TDK’s history and experience as the original inventor of hybrid RF absorber technology (ferrite tile + foam RF absorber) and being the only test chamber company to manufacture both the ferrite tiles and the foam RF absorbers, we are in a unique position to warrantee the best possible anechoic validation performance values.
TDK materials are lightweight, yet rigid and quite strong. TDK RF absorber material will not droop, crumble, breakdown, or change their physical or electrical characteristics even after 20+ years of use.
Our ISO-9001 and ISO-14001 facilities provide a tightly controlled manufacturing process assuring every part is consistent and avoids uneven resistive material distribution problems frequently observed in competitor materials.
TDK materials are also extremely safe and naturally very clean. You will not have to worry about potential fire hazards or toxicity issues with TDK materials.
A unique advantage TDK can offer you is the basis for our solutions stem from the fact TDK not only provides turnkey installations for our customers but TDK also owns and operates these same chambers to research, develop, test, and validate the many other products TDK manufactures.
As a firsthand user of test chambers for R&D and compliance testing of various products, we have a true understanding of the challenges you face. In addition to our simulation and modeling expertise to predict how a particular design will perform, we can share our experience with you to optimize the chamber design for the most practical, efficient, and real world use.
An example of NSA performance is shown in the graph (below). TDK can achieve very stable and consistent swept frequency values across the entire test volume area
An example of potential sVSWR performance is shown in the graph (below). With minimal set-up time and an optimized quantity of floor absorber between the sVSWR measurement antennas, TDK can achieve very stable and highly consistent swept frequency values across the entire test volume (quiet zone) area. sVSWR performance is accredited from 1 GHz to 18 GHz and for reference information, testing can be extended to 40 GHz.
