In most applications, the graph shows how signals change over time: the vertical (Y) axis represents voltage the horizontal (X) axis represents time. The intensity brightness of the display is sometimes called the Z axis.The Tektronix TDS784D oscilloscope's simple graph can tell you many things about a signal, such as: the time 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 not a malfunctioning component is distorting the signal, how much of a signal is direct current (DC) alternating current (AC) how much of the signal is noise whether the noise is changing with time.TDS784DPerformanceacteristics of the TDS784DForm FactBenchtopBandwidth 1 GHzNumber of Channels 4 chSimultaneous Channels 4 chSimultaneous Maximum Sampling Rate/ch 2 GSa/sOne ch. only max. sampling rate 4 GSa/sMax.
