Agilent Technologies 54825N 500MHz, 2GSa/s, 4ch Digital Oscilloscope
The Agilent Technologies 54825N 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.
