7313
The Tektronix 7313 is a 25 MHz storage oscilloscope mainframe introduced in 1972 that accepts two 7000-series vertical plug-ins and one 7000-series horizontal plug-in. There is also a rack-mount version, the R7313.
Project Engineer for the 7313 was John McCormick. Tim Boege did the electrical design while Cathy Weinstein worked on the mechanical design.

Internals
The direct-view bistable storage CRT (154-0682-02,-10,-12) is 8 cm tall and 10 cm wide. The upper half and lower half are independently controllable with regard to storage settings.
The low voltage power supply is linear. It produces +50 V, –50 V, +15 V, –15 V, +5 V, and +130 V.
The vertical amplifier is fully discrete.
The 7313 is the only 7000-series scope that doesn't use post-deflection acceleration, due to the low bandwidth. The CRT cathode voltage is -4 kV.
