1 Foreword
1.1 Introductions
X-431 GDS is a new generation of sophisticated and
integrated automotive diagnostic product with colorful screen
and powerful functions developed by LAUNCH, and Scopebox
is an optional function box for GDS, including automotive
oscilloscope and automotive ignition waveform.
Automotive oscilloscope can make the auto repair technician quickly
judged 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 capture 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 played back 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 indexes are the
amplitude (the maximum voltage of signal), the frequency (the cycle
