The Fluke PM3380A is a combined digital storage and analog oscilloscope in one instrument. Its 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. Features 2 channel 100 MHz Analog and Digital bandwith 100 MS/s single shot - up to 10 GS/s repetitive Autoset & Autoranging for horizontal and vertical settings Cursor measurements Trigger modes: Auto Single Edge TV (ntsc/pal/secam/hdtv) IEE488 Interface Frequency Display Graphical Display On Screen Menu
