Lesson 16: General Class Exxam Course G4B

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...
