The Tektronix 7612D is a digitizer that takes two vertical 7000-series plug-ins, typically the digitally programmable 7A16Ps.

It has a vertical bandwidth of 80 MHz. The sample rate is 200 Msamples/s. It uses a T7610 tube with an electron-bombarded semiconductor sensor as the digitizer, a form of scan converter.

Digitizing

The main advantage of the instrument is the capability of changing the sample rate during digitizing, see the returned raw data of the example pictured below.

Digitizing two waveforms on the 7612D...
...Channel A digitizes the waveform with a constant samplerate...
...On channel B the waveform is digitized with five different samplerates.
