Siepel
Manufacturer of anechoic chambers, shielded rooms and microwave absorber for the automotive, space, defence and commercial industries.
Anechoic Chambers for EMC
Siepel design and manufacture compliant and pre-compliant EMC chambers for testing to the following standards (and their equivalents): CISPR 16, IEC/EN 61000-4-3, CISPR 25, ISO 11452, DO160 and MIL STD 461.
Using their internal design team, Siepel can modify a chamber to suit your requirements.

Reverberation Chambers
Siepel provide a complete test system, inclusive of Reverb Chamber, software, RF instrumentation, on-site set-up and user training.
Based on the customer inputs (applicable standard, LUF, EUT dimensions, available instrumentation), SIEPEL can define the test facility as a whole and determine the required output power of the amplifiers, considering the losses from coaxial cables, harmonic filters, etc.
Antenna Measurement Chambers
SIEPEL offers anechoic chambers dedicated to Radio / Telecom and radar tests. Several models are available depending on the antenna to be tested and the measurements environment
- Near-field
- Far-field
- Compact ranges
- Radar Cross Section (RCS)
