The Tektronix 7104 is a 1 GHz, non-storage 7000-series oscilloscope mainframe that was introduced in 1978.  It replaced the 519 1 GHz oscilloscope first introduced in 1961.  It featured four slots for two vertical and two horizontal plug-ins.  The museum has a 7104 on display.

A micro-channel plate (MCP) CRT with quadrapole lens for deflection expansion was developed to significantly improve beam intensity at the high writing rate.  While previous CRTs used distributed plates for the horizontal deflection, the 7104 CRT used distributed plates for both the horizontal and vertical deflection.  The museum has a MCP CRT with the corner cut away on display with the oscilloscope.

It is not visible in this photo but at the museum you can see the microchannel plate through the cut out.

Val Garuts was the initial project leader and Gene Andrews took over leadership about half way through the seven year development.  John Addis was the Project Engineer for the vertical system including the design of the 7A29 and two of the ICs used in the vertical (one in the 7A29, the other in both the 7A29 and the main vertical amplifier).  Wink Gross designed two ICs for the main vertical amplifier.  Dave Morgan designed the mainframe horizontal amplifier and Art Metz designed the Z axis system.  Dennis Hall was the project leader for the CRT and Aris Silzars designed the vertical deflection plates and managed the acquisition of the microchannel plate.

We have two articles that describe the technical breakthroughs required in the development of this instrument.  Click on the images to open the PDFs.
