What is the function of a dummy load?

A dummy load serves the specific purpose of simulating an antenna during testing of radio equipment. When operating a radio transmitter, it is crucial to ensure that the device functions correctly without radiating signals, which can interfere with other communications or violate regulations.

By connecting a dummy load, the transmitter can direct its power into a resistive element that absorbs the energy, transforming it into heat. This allows operators to test the performance of the transmitter and other associated equipment without the need for an actual antenna, providing a safe environment to troubleshoot, adjust, and evaluate how well the equipment operates under various conditions.

The other options do not accurately describe the primary use of a dummy load. While signal strength, audio quality, and power consumption are important aspects of radio operation, they do not capture the fundamental role of a dummy load in facilitating safe and effective testing.
