Testing Products While Blocking Radio Frequency Just Got Easier

AES Insights

Radio frequency blocking environmental test chamber attenuation testingAfter working with many large consumer electronics companies, AES has recently developed a new product line that allows you to perform hot and cold climate testing while blocking RF waves from entering and escaping the test area.

ACTON, MA - May 23, 2019 - Associated Environmental Systems allows you to test products while blocking radio frequency (RF) waves without the use of an additional Faraday cage.  The FDR-501 and FDR-505 environmental test chambers offer 1 and 5 cubic foot workspaces that block RF waves from entering and leaving the workspace.

Previously, a device under test (DUT) needed to be placed inside a Faraday cage to block RF waves, significantly increasing testing time.  When a Faraday cage is used, conditioning a DUT requires much longer test cycles due to compromised air flow, uniformity, and the time it takes for the Faraday cage to radiate the temperature to the DUT.  While testing under these conditions, engineers also lost the ability to monitor their products.

Today, using an Associated Environmental Systems’ FDR test chamber provides blocking and trapping a wide range of radio waves. The factors that create RF blocking conditions are the outcome of thoughtful design work that combines high-grade steel, specialized door gaskets, and various mesh substrates to protect ports and air circulation paths from frequency waves moving in and out of the workspace. Using the FDR chamber can dramatically cut your test time, by as much as half.

Companies test their products within Associated Environmental Systems RF blocking chambers to:

  • block RF waves from entering and trap RF waves from escaping the chamber workspace while you take the measurements of your DUT at the temperature you require.
  • research and measure phantom waves and how the human body and other objects interrupt microwaves between a wireless phone and cell towers.
  • block a product’s radio frequency waves from escaping the chamber workspace effectively protecting employees who work in close proximity of RF products.
