The Industrial rated 20dB attenuator is an in-line, resistive attenuator also known as an RF pad. An RF attenuator will lower the amplitude of a signal by the rated amount where a signal may be too strong. This can be used to reduce that signal in order to get better quality signals, protect measurement equipment or other circuits. These can prevent signal overload in the amplifiers, receivers and detectors, adjusting the usable signal level to a valid range that is optimal.
