The test sites having an impact on the reliability of your measurements, it is necessary to validate them at the end of the installation.

Siepel measurement laboratory is accredited NF EN ISO/ IEC 17025 by the French Committee for Accreditation (COFRAC) and offers many accredited measurements of anechoic chambers:

• Shielding effectiveness (10 kHz - 40 GHz) according to EN-50147-1
• Normalised site attenuation (30 MHz - 1 GHz) according to CISPR-16.1.4
• Site VSWR (1 GHz - 18 GHz) according to CISPR-16.1.4
• Field uniformity (80 MHz - 6 GHz) according to EN-61000-4-3
• ALSE (150 kHz - 1 GHz) according to CISPR25

Siepel measurement laboratory is organised as an independant entity to ensure impartiality on results.

Your anechoic chamber must be calibrated by a test laboratory to verify its actual level of performance according to the standards.

It is also recommended to perform regular recalibration, even if the facility has not undergone major structural changes
