The 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, | |||
a pulse pattern marking crank angle in 10°, 60° and 360° increments, and a modified sine (6% second harmonic) representing piston volume as a function of crankshaft angle. | |||
The Engine Analyzer System was available from 1967 until 1975, when production of the 560 oscilloscope series was terminated. | |||
To allow the rotational function generator to be used with [[7000-series scopes]], Tek offered a combination of a modified | |||
timebase ([[7B53A]] MOD FB) and a [[TM500]] based power supply ([[PS501]]-1 MOD 730E) that were produced until 1985. | |||
