A signal generator is a device used to furnish current at a known frequency, often modulated, and to deliver a measured voltage at its terminals, used for testing.
A signal generator is a test instrument that produces an electrical signal at a known, controllable frequency, often with the ability to modulate the signal, and delivers a measured voltage at its output terminals. By providing a precise, known signal, the generator serves as a reference for testing, calibrating, and troubleshooting electronic equipment, communication systems, and cable. It allows engineers to observe how a device or cable responds to a defined input.
Because the frequency and level of the generated signal are known, a signal generator can be used to measure characteristics such as frequency response, gain, and loss in a system. This makes it a fundamental tool in the testing of communication and audio-visual equipment and cable.
In commercial and industrial contexts, signal generators support the testing that verifies the performance of cable and systems. Recognizing the instrument helps in understanding how signal characteristics are measured.

Recognizing the instrument helps in understanding how signal characteristics such as frequency response and loss are measured during the testing of communication and AV cable.
At Windy City Wire, an understanding of testing instruments like the signal generator reflects a focus on the methods that verify cable performance. Recognizing how a known signal is used to test a system helps illustrate how the quality of communication and AV cable is confirmed.
