Your Tektronix digitizing oscilloscope is a superb tool for acquiring, displaying, and measuring waveforms. Its performance addresses the needs of both lab and portable applications with the following features: 400 MHz maximum analog bandwidth on the TDS 460A 200 MHz maximum analog bandwidth on the TDS 410A and TDS 420A 100 Megasamples/second maximum digitizing rate Roll mode and triggered roll mode for display of slower waveforms Waveform Math — Invert a single waveform and add, subtract, and multiply two waveforms. On instruments equipped with option 2F, integrate or differentiate a single waveform or perform an FFT (fast fourier transform) on a waveform to display its magnitude or phase versus its frequency. Up to 30,000-point record length per channel (120,000-point optional) Full GPIB software programmability. GPIB hardcopy output. On instruments equipped with option 13, hardcopy output using the RS-232 or Centronics ports. On-board printer capability with option 3P instruments. Complete measurement and documentation ability Intuitive graphical icon operation blended with the familiarity of traditional horizontal and vertical knobs Four channels and four eight-bit digitizers on TDS 420A and TDS 460A. Two channels and two eight-bit digitizers on TDS 410A. On-line help at the touch of a button
