What is a signal generator?
- A A high-stability oscillator which generates reference signals at exact frequency intervals
- B A high-stability oscillator which can produce a wide range of frequencies and amplitudes
- C A low-stability oscillator which sweeps through a range of frequencies
- D A low-stability oscillator used to inject signal into a circuit under test
Correct answer: B — A high-stability oscillator which can produce a wide range of frequencies and amplitudes. From the official ISED question bank, verified word for word.
Why
A signal generator is a precise tool built to create radio waves at many different frequencies and power levels, making it ideal for testing and aligning equipment. The full explanation — and one for every question — is in Pro.
