An induction modulator is a piece of equipment used on starships and on Starbases.

One day in 2374 on Deep Space 9, Miles O'Brien was supposed to have finished calibrating the induction modulators. The next day, Kira Nerys asked him about it, and he said that he was having difficulty replacing the coil brackets. (DS9: "Wrongs Darker Than Death or Night")

In 2375, as part of an elaborate trading scheme, Nog traded Benjamin Sisko's desk for an induction modulator from Al Lorenzo. Nog then traded the induction modulator for a phaser emitter from the USS Musashi. (DS9: "Treachery, Faith and the Great River"}
