Editing Logic analyzer (section)

==History==
As digital computing and [[integrated circuit]]s emerged in the 1960s,<ref>{{cite web|title=The History of the Integrated Circuit|url=https://www.nobelprize.org/educational/physics/integrated_circuit/history/|publisher=Nobel Prize|access-date=28 November 2012}}</ref> new and difficult problems began to arise, problems that oscilloscopes had trouble handling. For the first time in computing history, it became essential to simultaneously view large numbers of signals. Early solutions attempted to combine hardware from multiple oscilloscopes into one package, but screen clutter, a lack of definite data interpretation, as well as probing constraints made this solution only marginally usable.

The HP 5000A Logic Analyzer, introduced in the October 1973 issue of the ''Hewlett-Packard Journal'', was probably the first commercially available instrument to be called a "Logic Analyzer". However, the HP 5000A was limited to two channels and presented information by means of two rows of 32 [[LED]]s. The first truly parallel instrument was the twelve channel HP 1601L, it was a plug-in for the HP 180 series oscilloscope mainframes and used the oscilloscope screen to present 16 rows of 12 bit words as 1s and 0s. It was introduced in the January 1974 ''Hewlett-Packard Journal''.<ref>{{cite web|url=http://hpmemoryproject.org/wb_pages/wall_b_page_12.htm|title=The Data Domain Transition|publisher=HP Memory Project|access-date=3 June 2015}}</ref>
