RF Shielded Environmental Test Chamber

By

Industry: Consumer Electronics

Testing Application: Environmental Stress & Radio Frequency Shielding Validation

A leading manufacturer in the consumer electronics industry contacted Associated Environmental Systems (AES) in need of a compact, bench-friendly environmental test chamber with integrated RF shielding to validate the functional reliability and signal integrity of high-frequency communication modules under extreme temperature conditions.

The challenge? The client required effective RF attenuation to isolate devices under test (DUT) from external ambient electromagnetic interference—and contain radiated emissions—without sacrificing precise thermal cycling capabilities. Furthermore, testing necessitated extensive multi-pin, high-speed data, and RF signal connections into the chamber workspace, requiring a fully customizable, filtered feedthrough interface panel alongside mobile, small-footprint lab placement.

The AES Solution

AES engineered our FDR-501 Temperature Only with Radio Frequency Shielding Environmental Test Chamber, a compact, high-performance floor model built to meet the unique demands of the application.

  • Integrated RF Shielding & Custom Interface Panel: Delivers high-performance RF attenuation (approximately 60 dB from 700 MHz to 2.6 GHz and 40–50+ dB up to 5.0 GHz) to ensure reliable electromagnetic isolation. The enclosure features a customizable interface panel capable of housing up to 9 RF-filtered feedthroughs, including SMA/BNC coax, shielded USB 3.x/Type-C, 10-Gigabit filtered Ethernet, and multi-pin D-sub connectors.
  • Precision Thermal Range & Stability: Features a wide operating range of -37°C to 94°C (-34.6°F to 201.2°F) with tight temperature stability of ±0.5°C at the sensor, driven by a single-stage refrigeration system delivering IEC rise rates of 3.14°C/min and pull-down rates of 1.0°C/min.
  • AESONE CONNECT® Instrumentation: Outfitted with AESONE CONNECT® software to enable seamless remote monitoring, automated profile management, and real-time data logging directly from a secure, customizable dashboard.
  • Space-Efficient Mobility & Modular Staging: Engineered with heavy-duty brake casters for effortless lab repositioning, a compact 1.13 cu. ft. workspace, and an auxiliary stainless steel shelf (13.25 in x 12.5 in) to maximize component density during batch testing.

Crafting Your Perfect Test Set-Up

This solution was custom-engineered to meet wireless and electronics testing demands in simultaneously mitigating RF interference while subjecting sensitive electronics to rigorous thermal stress. By combining certified UL-508A electrical construction, customizable EMI-filtered feedthrough arrays, and robust remote instrumentation, AES delivered a chamber that seamlessly integrates into dense R&D laboratories, accelerates design verification cycles, and ensures uncompromised device performance under real-world conditions.

This project highlights AES’s commitment to designing advanced, customized test solutions that help engineers push boundaries—supporting innovation in the telecommunications sector and beyond.
