The Tektronix 7613 is a 100 MHz variable-persistence storage oscilloscope that uses two vertical and one horizontal 7000-series plug-ins. There is also a rack-mount version, the R7613.
In the 76x3 family (7613, 7623 and 7633), the 7613 has the slowest writing speed specification. In storage mode, it is therefore more suited to lower-frequency work, or as a display for spectrum analyzers or sampling plugins.
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. Aiding the overall design effort were Dave McCullough and Dick Anderson.

Internals
The 7613's vertical output amplifier (below s/n 150000) is built around a 155-0080-00 hybrid. Later versions use the same vertical amplifier as used in the 7623A and 7633. Other custom Tek ICs used include 155-0011-00 clock & chop blanking, 155-0022-00 channel switch, and the 7000 series readout system chips.
The 7613, like the other 76xx models, has a linear supply with discrete regulator circuits, which does not provide +5 V for lights (A9) without modification.
The 7613 uses a CRT anode voltage of 7 kV, produced by a solid-state voltage multiplier fed by a transformer.
