Tektronix 2214 Oscilloscope, Digital: 20MHz,16MSa/s,4ch (Stand alone)
The Tektronix 2214 oscilloscope is a graph-displaying device – it draws a graph of an electrical signal. In most applications, the graph shows how signals change over time: the vertical (Y) axis represents voltage and the horizontal (X) axis represents time. The intensity or brightness of the display is sometimes called the Z axis.
