Tektronix TDS754D Oscilloscope,   Digital: 500MHz,2GSa/s,4ch (Stand alone) The Tektronix TDS754D oscilloscope is a graph-displaying device that draws a graph of an electrical signal which, in most applications, 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. Some Features of the Tektronix TDS754D Oscilloscope are: 500 MHz Bandwidth 4 GS/s Sample Rate Captures and Displays up to 200,000 Waveforms per Second 4 Channels 1% Vertical Accuracy 8-Bit Vertical Resolution 1 ns Peak Detect 1 mV/div Sensitivity Channel Deskew Record Lengths to 8 M Points Floppy Disk Storage Advanced Triggering 29 Automatic Measurements and Measurement Statistics FFT and Advanced Math Histograms Histogram Statistics Limit Test Copyright 2006 Trek Equipment Corporation - 1 888-873-5374
