The 568 is a [[sampling oscilloscope]] | 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. | ||

The 568 has multi-pin connectors on its rear panel that are routed to multi-pin connectors on the plug-ins. This is to support external control and measurement using, for example, a [[230]] and [[241]]. | ||
