The Tektronix 7623 is a 100 MHz analog multi-mode storage mainframe, introduced in 1972.
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 replaced the 7613, 7623A and 7633 in 1991.
It added a reduced scan mode to increase stored writing speed and is essentially a re-named 7633.
It was produced until the entire 7000 series was discontinued in 1992.
There were also R7623(A,B) rack-mount versions.
Project Engineer for the 7613 and 7623 was Bill DeVey under direction of Oliver Dalton. John Durecka did the electrical design. Doug Giesbers, Ed Wolf, and Chuck Davis provided the mechanical design. The CRT for the 7623 was developed by Gary Siewell, Chris Curtin, and Wes Hayward. Aiding the overall design effort were Dave McCullough and Dick Anderson.

Internals
The 7623 uses a Transfer storage CRT which includes an internal, fast-responding storage mesh. In fast mode, the time base is inhibited after a sweep, and the transfer cycle is started. Individual sweeps therefore occur in about one-second intervals.
The vertical output amplifier is built around a 155-0080-00 hybrid in the non-A version. The 7623A vertical amplifier is a discrete design with bridged T-coils. Other custom Tek ICs used in the 7623 include 155-0011-00 clock & chop blanking, 155-0022-00 channel switch, and the 7000 series readout system chips.
The 7623, like the other 76xx models, has a linear supply which does not provide +5 V for lights (A9) without modification.
