Figure 1-49. Ignition Simulator, SK-D-4850-15 (7916123).
The Ignition Simulator (fig. 1-49) is used to simulate an automotive ignition system in the calibration of tachometers that
receive their excitation from a magnetic pickoff connected to the spark plug high voltage cable. The ignition simulator
produces a high voltage to fire the spark plug over the frequency range of 1 to 200 hertz when driven by a square wave
generator and a dc power input between 8 and 18 V.
