The '''Tektronix 7623''' is a 100 MHz analog multi-mode storage mainframe, introduced in 1972.<br />The '''7623A''' facelift in 1975 increased standard writing speed to 150 div/µs (from 100 div/µs for a 7623 without option 12). Front panel controls were changed in the 7623A, too. The '''7623B''' version, specified at 100 MHz, added a reduced scan mode to increase stored writing speed (essentially it was a re-named [[7633]]). It replaced the [[7613]], 7623A and [[7633]] in 1991.  There were also '''R7623'''(A,B) rack-mount versions.
