The Tektronix 7D20 is a two-channel digitizing plug-in for [[7000-series scopes]]. It is a triple-width plug-in and provides both vertical and horizontal signals to the scope. | The '''Tektronix 7D20''' is a two-channel digitizing plug-in for [[7000-series scopes]].

The 7D20 uses an analog shift register (CCD) for high-speed signal acquisition, and then digitizes the stored analog signal at a lower speed. This design allowed the 7D20 to capture single-shot events at 40 MSamples/s even though this exceeded the speed of ADCs of the time. The 7D20 can digitally store waveforms and has a [[GPIB interface]]. A microprocessor (68B09) in the plug-in controls most of its functions. | The 7D20 uses an analog shift register (CCD) for high-speed signal acquisition, and then digitizes the stored analog signal at a lower speed.
