What can measure resistance, capacitance, and inductance with precision?

The option that accurately measures resistance, capacitance, and inductance with precision is the alternating-current bridge. This type of instrument is specifically designed to measure these parameters across various frequencies, providing highly accurate results. It uses a balanced network to determine the values of these components by comparing them against known standards.

Unlike a digital multimeter, which is versatile and can measure resistance and capacitance but may have limitations when it comes to inductance over a range of frequencies, an alternating-current bridge is optimized for precision in all three types of measurements. This makes it the preferred choice for applications requiring high accuracy, such as in laboratory settings or when testing and calibrating electronic components.

The other options, while they perform important functions, do not match the precision measurement capabilities of an alternating-current bridge. An analog meter, for example, is often less precise due to its reliance on needle movement, and signal generators primarily generate signals rather than measure passive component values.
