12 Oscilloscope (Toolbox)
12.1 Introduction
The Scopebox is an optional add-on module of X-431 PAD III, including
automotive oscilloscope and automotive ignition waveform.
Automotive oscilloscope can make the auto repair technician quickly judge the
faults on automotive electronic equipment and wiring, and the oscilloscope
sweep speed is far greater than the signal frequency of such vehicles, usually
5-10 times of the measured signal. The automotive oscilloscope not only can
quickly acquire the circuit signal, but also can slowly display the waveform to
observe and analyze. It can also record and store the tested signal waveform
which can be recalled to observe for the fast signal, having great convenience to
failure analysis. Either high-speed signal (e.g.: Injection nozzle, intermittent fault
signal) or the slow-speed signal (e.g. the throttle position change and the oxygen
sensor signal) can be observed through automotive oscilloscope in an
appropriate waveform.
The electronic signal can be compared and judged via measuring five
parameters indexes. The five parameters are the amplitude (the maximum
voltage of signal), the frequency (the cycle time of signal), the shape (the
appearance of signal), the pulse width (the duty cycle or the time range of signal),
and the array (the repetition characteristic of signal), which can be tested,
displayed, saved by the automotive oscilloscope. Via the waveform analysis can
further detect the circuit fault on sensors, actuators, circuits, and electronic
control units, etc.
