A self-contained switchable, incremental attenuator device for interposing in a two line power circuit to attenuate the power level for proper power matching. The device includes a series of modulized, individually switchable attenuator circuits of differing attenuation values mounted upon a pluggable card for interfacing with input and output connectors of a circuit. The attenuation values of the sections are selected such that manipulating the switches will allow attenuation of the power level in the circuit by an integral multiple of a given base incremental value within a given range. The attenuator device is designed to mate with a mounting device for holding the attenuator in contact with the circuit connectors.
