In the early 1960s, the '''Tektronix Engine Analyzer''', a next generation of products based on optoelectronic rotational encoders, pressure transducers, and ignition pick-off probes, was commercialized. | |||

The Engine Analyzer was applied to measurements on [[wikipedia:Internal combustion engine|Internal combustion engines]]. Possible displays include | |||

The [[015-0108-00 | Rotational Function Generator]] consists of a rotating film disk that is mechanically linked to the engine. | |||
Through three printed, optically sensed patterns, it provides three selectable signals – a sawtooth pattern linked to the crank angle, | Through three printed, optically sensed patterns, it provides three selectable signals – a sawtooth pattern linked to the crank angle, | ||
