OSCILLOSCOPE
An oscilloscope is a laboratory instrument commonly used to display and analyze the waveform of electronic signals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time.
FUNCTION GENERATOR
A signal or function generator is a device that can produce various patterns of voltage at a variety of frequencies and amplitudes. A common use is to test the response of circuits to a known input signal. Most function generators allow
you to generate sine, square or triangular AC function signals.
