二手 Tektronix TDS684B-13-1F-2F 在 玛丽湖, 佛罗里达, 美国

Tektronix TDS684B Oscilloscope, Digital: 1GHz,5GSa/s,4ch (Stand alone)
The Tektronix TDS684B 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 Tektronix TDS684B 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...
