The oscilliscope is a valuable tool in analyzing time varying currents. To understand these currents, we must first think of them as a sinusoidal wave or at least that they behave like one. The screen is a grid onto which the wave is projected via beaming electrons onto its surface which is cotated in phosphor and produces visible light as a result. The scope can be used to see the effects (such as DC offset) of various alterations can have on a current.
By connecting it to a function generator, the oscilliscope started to churn out the resulting graphs. The X axis represents the time and the Y axis represents the amplitude or magnitude of the current. We were able to measure both a sinusoid and a square wave (DC coupled). The last part of the lab involved measurement of two mystery signals.
