V Technical Textiles has created a revolutionary new Soft Sided Portable Reverberation Chamber constructed of highly conductive textile material, the walls of which reflect radio waves. A metalized textile stirrer is also used in the chamber to yield a non-directional or diffuse RF field inside of the chamber. This is a Vibrating Intrinsic Reverberation Chamber (VIRC), which means that the field has radiofrequency sufficient to adversely affect the device subjected to it. A reverberation chamber is used for testing in the aerospace, automotive, and military/defense fields for electrical immunity testing, in an effort to assure that the function of the Device Under Testing (DUT), is unaffected by radiofrequency assault and will continue to operate properly in this challenging environment. The VIRC also checks emissions from the DUT, assuring that it doesn’t emit too much radiofrequency “noise” of its own that would disrupt other electronic systems in the vicinity, helping to create a stable shared electronic environment. The uniformity of the field assures that all surfaces of the DUT are painted with each 360-degree revolution of the signal stirrer, resulting in better test repeatability.
V Technical Textile’s reverberation chamber can be used with many of the available software systems that are used by the aerospace, automotive, and military/defense communities in testing their equipment for data collection, statistical analysis, and generation of test reports. The reverberation chamber is typically used to help test a device for compliance with MIL STD 461 and DO 160. These tests measure both RF emissions of the DUT and the susceptibility of the DUT to RF interference while performing its normal tasks.
The VTT Reverberation Chamber is much less expensive than the legacy “dedicated room” reverberation chambers. An additional plus is that this chamber is able to be taken down and stored when it’s not actively in use for testing, allowing alternative use of precious space. These enclosures can be made to order, for any size device depending on the needs of the customer. 9000 Series Portable RF Shielded Enclosure Reverberation Chamber.
