A dip meter supplies the radio frequency energy which enables you to check:
- A the adjustment of an inductor
- B the resonant frequency of a circuit
- C the calibration of an absorption-type wavemeter
- D the impedance mismatch in a circuit
Correct answer: B — the resonant frequency of a circuit. From the official ISED question bank, verified word for word.
Why
A dip meter works by sending radio frequency energy into a circuit and detecting when the circuit absorbs that energy most strongly, which happens exactly at its resonant frequency. The full explanation — and one for every question — is in Pro.
