Tektronix TDS3032 Oscilloscope, Digital: 300MHz,2.5GSa/s,2ch (Stand alone) The Tektronix TDS3032 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 TDS3032 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. # 2 independent 300 MHz channels # 2.5 GS/s Sample Rate on all Channels # 10K Record Length # 9-Bit Vertical Resolution # Full VGA Color LCD # Very small and lightweight 15"x7"x6", 7 lb. # Battery option allows remote operation # 25 Automatic Measurements # Multi-language User Interface # QuickMenu Graphical User Interface for Easy Operation # Built-in Ethernet Port # e*Scope Web-based Remote Control # WaveAlert Automatic Waveform Anomaly Detection # Advanced Analysis Module for Detailed Design Analysis # Telecommunications Mask Testing # FFT Analysis # Two Video Modules for Testing and Troubleshooting # Limit Testing for Rapid Go/No-Go Testing # Advanced Triggers including Glitch, Runt and Logic # Plug-in Printer for Portable Documentation of Results # TekProbe™ Level II Interface Supports Active, Differential and Current Probes # Centronics Port Standard on all Models for Quick, Convenient Hardcopies # Built-in Floppy Disk Drive For Easy Storage and Documentation
