In prototyping of electronic circuits, a decade box is a type of test equipment that can be used to substitute the interchanging of different values of certain passive components with a single variable output. Decade boxes are made for resistance, capacitance, and inductance, the values of which can be increased incrementally by way of switching the [clarify] for the input and output throughout a series of the respective components. The interface for these devices will usually consist of dials or adjustable tape counters, and are operated in-circuit and without any external power source.
