The '''Tektronix 5000-series (5K)''' was introduced in 1971 as a series of lower-cost laboratory oscilloscopes with versatile plug-ins.  They generally have larger display screens than the more expensive and higher performance [[7000-series scopes|7000-series]], but have very low bandwidth in comparison.

The 5000-series (5K) was introduced  in 1971 as lower-cost, laboratory oscilloscope
5000-series mainframes consist of an acquisition unit (the [[5103]] or [[5403]]) containing
instrumentation with plug-in versatility.  This series generally has larger display
the plug-in compartments and low-voltage power supply, and a display unit (e.g., the
screens than the more-expensive and higher-performance [[7000-series scopes|7000-series]],

but also has very low bandwidth in comparison. 
 
The idea was that the display unit could be sold separately for custom integrated uses by other manufacturers at a lower cost than the [[:Category:600_series_CRT_monitors|600-series monitors]], and at the same time provide
a larger display area. 
 
Within the Tektronix product line, the D10 and D11 display units (non-storage and bi-stable storage, respectively) are also used in constructing the [[577|577 semiconductor curve tracer]],


Unlike other Tektronix products other than the [[7704A]] in the 7000-series,  the

But within the 5000-series, this led to documentation problems as each oscilloscope
ended up with two model numbers and two serial numbers.  In 1977, the scopes that
were listed as “5103/D13” for example, with a serial number for each half, Tek
