National Technical Systems
A reverberation chamber, sometimes known as a mode tuned/mode stirred chamber, is a shielded enclosure or resonant cavity for RF testing. This chamber is statistically isotropic, random polarity, having RF uniformity within specified limits. Typically a reverberation chamber has a paddle (or tuner) which stirs the field, randomizing the boundary conditions.

LBA Group, Inc
EMI (Electromagnetic Interference) is often used interchangeably with RFI (Radio Frequency Interference). However, EMI can be any frequency of electromagnetic noise, whereas RFI is a relatively narrow range of electromagnetic noise on the EM spectrum. EMI Shielding can be used to mitigate electric and magnetic radiation across various spaces. Radio Frequency (RF) Shielding can be used to mitigate RFI with specifically designed enclosures that can block RFI. As well, RF Shielding can include application of RF Shielding paints, fabrics, and other materials.

Adaura Technologies
RF leakage through Ethernet and USB cables can destroy even the best RF enclosures and chambers. The need for filtering in the ever congested RF environment requires special filters that can pass USB 2.0 and 10/100/1000 Mbps Ethernet signals and filter out unwanted higher frequencies such as cellular and WiFi. The Adaura Technologies USB/Gigabit Filters provide one GigE and one USB 2.0 pass-through connections while filtering out other RF up to 8GHz. It has a small form factor to allow easy installation. It is a most cost effective solution for a clean chamber set up. In a typical chamber, WiFi signals are reduced to <-100dBm with this filter installed.

Sonnet Suites -
Sonnet Software
The Sonnet® Suites™ develop precise RF models (S-, Y-, Z-parameters or extracted SPICE model) for planar circuits and antennas. The software requires a physical description of your circuit (arbitrary layout and material properties for metal and dielectrics), and employs a rigorous Method-of-Moments EM analysis based on Maxwell's equations that includes all parasitic, cross-coupling, enclosure and package resonance effects.

Adaura Technologies
The AD-USB R3 is AdauraTech’s latest design in the AD-USB series of programmable RF attenuators. Combining all the best features of the previous models, the R3 is the new series flag ship. With a completely custom machine aluminum enclosure, the R3 boasts 95dB of attenuation. The addition of Ethernet allows EASY implementation into the most modern of test setups by allowing network control via HTTP web interface or direct Telnet while the USB port powers the device and allows for serial communication.

RF shield testing: IEEE-299, MIL-STD-285, NSA 65-6CTIA CATL certification testing: Probe symmetry and amplitude ripple measurements following Test Plan for Wireless Device Over-the-Air PerformanceAnechoic material test, inspection, remediation: VSWR, inverse spherical nearfield testing of installed material and NRL arch screening tests of individual absorber pieces We can also provide in-process testing of welded steel shielded enclosures with a test technique based on ASME BPVC vacuum box testing—confirm quality of RF welds before the shield envelope is complete. We developed this method for testing the Navy’s Advanced System Integration Lab (ASIL) chamber at Patuxent River, shaving weeks off the construction/testing schedule.
