567

The Tektronix 567 is a sampling scope made by Tektronix in the mid 1960's, first sold in 1963. It has a digital plug-in unit, the 6R1 or 6R1A, that can be used to measure waveform characteristics such as rise time. This digital unit provides a go/no-go output based on waveform characteristics. This feature make the 567 particularly useful in production testing, for example, binning logic gates based on their speed. The 567 came after the 661 and before the 568.

The 567 has three plug-in compartments. The left compartment holds a 3S-series sampling vertical unit. The center compartment holds a 3T-series sampling sweep unit. The right compartment holds the digital unit. It is possible to operate a 567 without the digital unit but in that configuration it provides the same functionality that a 561 provides.
