568

The 568 is a sampling oscilloscope that was introduced in 1967 that 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. 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.
