The LeCroy 9310C 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.
The LeCroy 9310C oscilloscope's simple graph can tell you many things about a
signal, such as: the time and voltage values of a signal, the frequency of an
oscillating signal, the moving parts of a circuit represented by the
signal, the frequency with which a particular portion of the signal is occurring
relative to, other portions, whether or not a malfunctioning component is
distorting the signal, how much of a signal is direct current (DC) or
alternating current (AC) and how much of the signal is noise and whether the
noise is changing with time.
