What does a dip meter do?
- A It measures transmitter output power accurately
- B It measures field strength accurately
- C It measures frequency accurately
- D It gives an indication of the resonant frequency of a circuit
Correct answer: D — It gives an indication of the resonant frequency of a circuit. From the official ISED question bank, verified word for word.
Why
A dip meter works by coupling energy into a circuit and showing a drop in its own signal when the circuit naturally vibrates at the same frequency, which is called resonance. The full explanation — and one for every question — is in Pro.
