An anechoic chamber is an echo-free room engineered to absorb reflections of sound or electromagnetic waves completely. The term ‘anechoic’ is derived from Greek, meaning ‘no echo’. These chambers are carefully designed with special, sound-absorbing materials that line the floor, walls, and ceiling to mute echoes.Traditionally Taper chambers are constructed using a square based pyramidal shaped taper. The taper is then shaped into an octagon and finally transformed into a cylindrical launch section. This approach is related to the manufacturability of different absorber cuts.

A reduction in the RBW setting of 10X (e.g. 100 kHz to 10 kHz) will lower the DANL by around 10dB. By going to very low RBWs of 1 kHz or even lower, it is possible to expose signals that would otherwise be 10-20dB below the displayed noise floor of your analyzer. Reducing RBW Lowers Noise Floor and Exposes Input Signal.
