The '''Tektronix 567''' is a [[sampling oscilloscope]] mainframe [[introduced in 1962]]. | |||
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 makes the 567 particularly useful in | |||
production testing for tasks such as binning logic gates based on their speed. | |||
The 567 came after the [[661]] and before the [[568]] and its associated [[230]] Digital Unit. | |||
According to [[Stan Griffiths]], | |||
