The Tektronix TDS8000 is a modular digital sampling oscilloscope engineered for acquisition and analysis of high-speed electrical and optical signals. It delivers 14-bit vertical resolution across a configurable multi-channel architecture supporting up to 8 simultaneous inputs—either 8 electrical channels or a hybrid configuration of 2 optical and 6 electrical channels. The instrument accommodates up to four dual-channel electrical and two single-channel optical sampling modules, with bandwidth and rise time determined by the installed modules. Sample intervals reach as low as 10 femtoseconds, enabling precise characterization of fast transients and high-frequency waveforms in communications, semiconductor development, and data storage applications.
