7612D
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.
