An attenuator is a passive component that is inserted into the signal path to reduce the amplitude or the power by one level.
Depending on the type of signal, a distinction is made between fixed attenuators and programmable attenuators.
Attenuators have a constant attenuation over a wide frequency range. A signal attenuation of 20dB means an attenuation of the transmitted power to 1/100.

Attenuators - how can I improve my test port?

Superior performance - wonderful in competition - threatening in high frequency technology. With attenuators, small components that are screwed into the cable connections between devices, they master the problem. Unwanted powerful signals are thus reduced to a fixed degree so that they can be processed at the following input without damage or overload. Attenuators can also be used for power attenuation in front of terminating resistors or for impedance and port matching at inputs in the physical power frame.
