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.

After that, there is no numbering convention - unlike the 7000s, all 5xxx mainframes have three compartments, which eliminates any special meaning that would be attributed to the last digit of the model number.

Four plug-ins of the 5000-series directly mirror “twins” in the 7000-series: the
[[5CT1N]] ([[7CT1N]]) curve tracer, [[5A22N]] ([[7A22]]) differential amplifier,
[[5A13N]] ([[7A13]]) differential comparator, and the [[5S14]] ([[7S14]]) sampler. 
Front panel layout and function of these “twins” are nearly identical,
although the bandwidth of the 7A13 is significantly higher than its 5K counterpart. 
Note also that the 7000 plug-in interface is significantly different from the 5000 series,
so the plug-ins are not identical but may use common parts together with adapters,
like in the 7S14 that [[Media:Tek-7s14-right.jpg|contains the full 5S14 board]].
