The Tektronix 7633 Storage Oscilloscope is a 100 MHz mainframe that captures and analyzes high-speed transient signals using a Tek T7630 Transfer Storage Tube with P31 phosphor. The instrument provides four distinct storage modes—BISTABLE, VAR PERSIST, FAST BISTABLE, and FAST VAR PERSIST—each delivering different writing speeds optimized for signal retention and display persistence. Three display modes (NON STORE, STORE, SAVE) and selectable scan options enable flexible signal observation and measurement.
