The Tektronix Engine Analyzer consists of a 561A oscilloscope or a 564 storage scope, a specially designed Engine Analyzer Timebase (a modified 2B67) with a rotational function generator input, and a modifIed 3A74 4-channel amplifier providing separate inputs for pressure (with a charge preamplifier), ignition, vibration, and crank-shaft rotation marker.
The instrument package includes a rotational function generator, pressure and vibration transducers, ignition pickoff, magnetic pickup, cables and carrying case.
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.
Possible displays include
- Pressure vs. time
- Pressure vs. volume
- Pressure vs. crank angle
- Vibration analysis
- Ignition analysis (timing, point arcing, spark plug condition etc.)
