Which device generates a tone on one end of a conductor to identify it at the opposite end?

The device that generates a tone on one end of a conductor to identify it at the opposite end is an inductive amplifier. This tool works by sending a specific signal or tone down a conductor, which can then be detected and translated into sound or visual cues when reached at the other end. This capability is essential for tracing wires in complex installations, helping technicians quickly identify specific conductors among numerous cables, especially in environments where cables may be bundled closely together.

Signal tracers can also facilitate cable tracing, but they primarily pick up existing signals rather than generating a tone themselves. Multimeters and oscilloscopes serve different functions primarily related to measuring electrical parameters, such as voltage, current, and waveform analysis, rather than tone generation for identification purposes.
