Your Tektronix TDS 800 Digitizing Oscilloscope is a superb tool for acquiring, displaying, and measuring waveforms. Its performance addresses the needs of both benchtop lab and portable applications with: ■ 8 GHz maximum repetitive analog bandwidth in TDS 820 Option 1D; 6 GHz in the standard TDS 820. ■ Pretrigger view (not available with Option 1D). ■ Acquisition channels—The TDS 820 has two. You may use and display all channels simultaneously. ■ Two14-bit digitizers. ■ Up to 15,000-point record length per channel. ■ Waveform Math—Invert a single waveform and add, subtract, and multiply two waveforms. On option 2F equipped instruments, integrate or differentiate a single waveform or perform an FFT (fast fourier transform) on a waveform to display its frequency spectra. ■ Full GPIB software programmability. GPIB hardcopy output. On instruments equipped with option 13, hardcopy output using the RS-232 or Centronics ports. ■ Complete measurement and documentation ability. ■ Intuitive graphical icon operation blended with the familiarity of traditional horizontal and vertical knobs. ■ On-line help at the touch of a button.
