PLUG-IN ADJUSTABLE ATTENUATOR CONSTRUCTION Abstract of the Disclosure A plug-in adjustable attenuator including a receptacle base adapted to receive different selected pairs of mating plug- in units, one for setting integral values of attenuation, and the other for setting fractional values. Electrically, the attenuator comprises a pair of series-connected balanced resis- tance networks, one establishing integral attenuation values, and the other, proper fractional values in a line to which the attenuator is connected. In addition to other advantages, employing separate networks for integral and fractional values of attenuation greatly reduces the number of plug-in parts needed to cover a desired attenuation range in small increments.
