FDR-505 - Temperature Only


The FDR-505 test chamber offers the ability to test frequency generating devices within a shielded environment, effectively shielded frequencies from entering inside and from escaping out of the test chamber workspace.

an independent test facility to certify attenuation. Your chamber comes with a test report showing attenuation performance.

Powerful and Consistent Radio Frequency Blocking

  • Cellular, metallic, chromatic gaskets and conductive adhesives create a sealed workspace
  • RF Honeycomb shielded grill keeps the circulation motor cool
  • Electrical wires into the working volume travel through special RF filters
  • Standard and Customer requested RF-rated connectors are installed on a side-mounted interface plate providing a shielded pass-through grid for communication with the device under test. (DUT)
  • Temperature range -37°C to +94°C (-34.6°F to +201.2°F)
  • Wide attenuation range encompassing many products
  • Independently certified for accuracy

STRUCTURE.  The internal workspace is lined with type 304 stainless steel for a vapor-tight internal construction. The exterior has a durable powder-coat finish over heavy-gauge steel for a long-lasting clean look. Between the two layers is highly-efficient, low k-factor, thermal insulation. This chamber is built to last for many years.

CIRCULATION SYSTEM.  Air circulation is crucial for environmental testing. The FDR-505 Test Chamber has a proprietary baffle and fan design combination. This optimizes temperature conditions within the workspace. 

HEATING SYSTEM.  FDR test chambers feature heating systems equipped with open ceramic-core nichrome heaters for reliable and accurate temperature control within ±0.5°C.

COOLING SYSTEM. The cooling system in the is FDR-505 consists of a self-contained, compact, single-stage, mechanical refrigeration system with an air-cooled condenser. An optional water cooling condenser is available.

Add boost cooling with liquid LN2 or CO2 to shorten pull-down times; it's a great option for stress tests that require rapid cooling.

INSTRUMENTATION.  FDR Series Test Chambers have incorporated the AESONE CONNECT creating a robust connected device for a standard and uniform interface making operation easier. Learn more in the Instrumentation Tab below.

  • Digital Set High-Temperature Safety - shuts down the test chamber if it goes over a certain temperature

Optional Features

  • Shelf Modification (placement, size, number)
  • LN2 Boost Coo l
  • CO2 Boost Cool
  • Custom Port Configuration and Attachments
  • Noise Reduction Package
  • High/Low-Temperature Safety - manual-control, digital-set temperature safety shuts-down test chamber if it goes over or below a specified temperature
