Here is lesson 16 covering the G4B section of questions form the question pool. This lesson primarily deals with test equipment. The lesson is straight forward, but I will give you a run down of the various test equipment covered. Remember, these are very simplified definitions for the intent of identifying the correct answer on the exam.
- An Oscilloscope is used to measure waveforms.
- A signal tracer is used to identify inoperative circuits in a receiver.
- A noise bridge measures impedance and is connected between a receiver and an antenna of unknown impedance.
- A field strength meter will measures RF field strength and can be used to measure RF output.
- A dip meter measures the resonant frequency of a circuit.
Until lesson 17...
