The Tektronix 067-0657-00 Normalized Ramp Generator is a calibration plug-in for 7000-series scopes.

It provides calibrated sweep rates from 0.5 ns/Div to 50 ns/Div (in a 1–2–5 sequence) plus 1 μs/Div and 1 ms/Div.

The calibration fixture is triggered from an external signal (such as a trigger output from a time-mark generator) applied to the front-panel TRIG IN connector.

Internals

The 067-0657-00 was the result of some fundamental research by Bruce Hofer inspired by production issues in the calibration of early 7904 scopes. This lead to a new sweep circuit that uses current steering in a differential pair to start the charging of the timing capacitor as is discussed in patent 4009399. The sweep circuit in the 067-0657-00 follows the patent application but does not implement the baseline stability circuit, which was incorporated in the 7B92A.
