The Tektronix 7612D is a digitizer that takes 7000-series plug-ins.

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

Key Specifications

Sampling Clock	200 MHz ±0.0035%
Sampling Rate	1 S/s - 200 MS/s
Bandwidth	90 MHz
Effective number of bits	7.8 @ 300 kHz 6.0 @ 20 MHz 4.0 @ 80 MHz
Memory	2048 8-bit words/channel

Digitizing

The main advantage of the instrument is the capability of changing the sample rate during digitizing. The returned raw data of the example can be found here: File:Tek 7612D digitizing settings data.txt

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.
