Tektronix 7633

This Scope Mainframe is a fast storage scope that is designed for fast writing rate storage applications.

It operates in three display modes NON-STORE, STORE and SAVE and four storage modes FAST VAR PERSISTS, FAST BISTABLE, VAR PERSISTS, BISTABLE.

The device can be worked also in a reduced scan mode (the screen appears smaller, resulting in an higher writing speed if necessary).

This was an excellent instrument in times without digital storage scopes. It is still a good general purpose oscilloscope for many applications.

A good choice together with the spectrum analyzer series (e.g. 7L12) or for low horizontal deflection rates and fast storage applications.
