SHIELDED CABINETS V5– 20.10.2014

SHIELDED CABINETS

The great evolution of the wireless technologies over the

last few years creates a more and more perturbed

electromagnetic environment, over a wide frequency range.

During R&D or final testing of electronics or radio products,

this polluted environment can be the source of various

unwanted interferences or emissions.

These shielded cabinets enable to isolate the equipment to

be tested, with a shielding effectiveness of up to 120dB.

Electromagnetic absorbers (ferrites or pyramids) can be

added for radio testing, for example.

Adapted to the technical specifications of our customers,

SIEPEL shielded cabinets are equipped with various options

and feedthroughs.

1/2

Suitable for small RF / microwave devices and/or antennas

Custom design and dimensions available

Knife edge shielded door for high shielding effectiveness performances (120 dB @ 1 GHz) up to 40 GHz

Upgradeable and flexible

Ruggedized for lab life

Easily movable and space saving

Cabinet can be fitted with various available feedthrough: RF connectors, honeycomb air vents, fibre optics

waveguides (pipe penetrations), data signals filters, power filters (AC, DC) with internal outlets, control line

filters, data lines filters (up to 2 Mbits/s), USB / Ethernet / LAN / RS232 fibre optics converters, see-through

shielded window…

Electromagnetic absorbers: In order to create a quiet and stable electromagnetic environment and to ensure a

high repeatability of measurements, cabinets can be internally lined with electromagnetic absorbers:

- Ferrite absorbers - frequency range 30 MHz – 1 GHz (see Ferrite absorbers technical data sheet)

- Foam pyramidal absorbers - frequency range 800 MHz – 40 GHz (see Broadband pyramidal absorbers

technical data sheet)

SHIELDED CABINETS V5– 20.10.2014

FONCTIONAL TESTS

Shielding effectiveness: 120 dB at 1GHz without window >70 dB at 1GHz with window

Usual external dimensions: L x W x H = 375 x 325 x 250 mm

Equipment’s: o Shielding only o System of opening and closure (lock) of door by handle of lifting o Shielded window

Advantages: o Visualization of EUT from the outside through an shielded window o Honeycomb installed on the lid for the passage of a not conductive tool

allowing the manipulation of the switching’s during the test through the honeycomb stitch
