Normalized Site Attenuation (NSA)


Normalized Site Attenuation (NSA)

The NSA measurements (30MHz to 1GHz) are carried out to determine suitability of a Semi Anechoic Chamber or an Open Area Test Site for undertaking the Radiated Emissions test as per CISPR 16-1-4.
BNN has Antennae/equipment with traceable calibration and trained engineers to undertake NSA measurements for Open Area Test Site (OATs), Semi Anechoic Chambers (SAC), Fully Anechoic Rooms (FAR).
The test frequency points and locations are selected based on the instructions given in the test standard and the site configuration.
Measurements are undertaken as per following NABL/17025 accredited scope:-
(a) CISPR 16-1-4:2020
(b) ANSI 63.4:2017
