TEKTRONIX TDS8000

The Tektronix TDS8000 digital sampling oscilloscope offers a wide range of on-board measurement and waveform-processing capabilities. With excellent measurement repeatability, exceptional vertical resolution and fast waveform acquisition and display update rates, the Tek TDS8000 is a powerful measurement tool for semiconductor testing, TDR characterization of circuit boards, IC packages and cables and high-speed digital communications.

The Tektronix TDS8000 scopes’ timebase provides equivalent time sweep speeds from 0.5 ps/div to 5 ms/div with record lengths from 20 to 4000 points and a sample interval of 10 femtoseconds (0.01 ps). In addition, the TDS8000 sampling oscilloscopes’ timebases can be locked to a 10 MHz reference providing greater long-term stability. This capability also allows multiple TDS8000s to be synchronized to other test equipment and/or the device-under-test.
