Features
An Oscilloscope could be used to monitor the test points and the output of systems or modules. A function generator injects the input or simulates a input condition. It could be Sine Wave, Triangle Wave, Ramp or Square wave. Frequency, Amplitude and Duty cycle (square) are variable settings.
For radios and amplifiers a simpler set is used it is called "Signal Injector" and "Signal Tracer". In Digital System a Pulse Generator and a Logic Probe may be used.
