Terahertz frequencies range from 100 GHz to 10,000 GHz, or 1 trillion hertz (Hz) to 10 trillion Hz, which allows for advanced applications. These frequencies are crucial for high-resolution testing in specialized fields and are often used in areas like telecommunications, medical imaging, and security. The N9040B currently supports frequencies up to 50 GHz, so it does not cover terahertz frequencies.
