The 568 is a [[sampling oscilloscope]] that was [[introduced in 1967]] that takes 3S- and 3T-series plug-ins.   
The '''Tektronix 568''' is a [[sampling oscilloscope]], [[introduced in 1967]], which takes 3S- and 3T-series plug-ins.   
Although it was intended to be used for sampling, it can also be used with non-sampling plug-ins of the 3A and 3B series.
Although it was intended to be used for sampling,
it can also be used with non-sampling plug-ins of the 3A and 3B series.


Like the [[561]] and [[564]], the 568 does not contain vertical or horizontal amplifiers. The plug-ins directly drive the deflection plates. The 568 has multipin connectors on its rear panel that are routed to multipin connectors on the plug-ins. This is to support external control and measurement using, for example, a [[230]] and [[241]].

The typical cable for connecting the [[568]] to the [[230]] is the [[012-0119-01]].


Two sampling heads can be interfaced directly to the 568 using the [[012-0130-00]] cable, or

As a part of the test and measurement systems,
the 568 was sold at least until 1986.
A modification, 708P, was available for the 568 to give it a head multiplexer instead of a CRT. Head multiplexer is similar with [[286]]
