Oscilloscope

Course Details

For some decades, the electronic systems in a vehicle have been increasing in number and sophistication. There is also increasing interdependence between these systems through the multiplexing networks which allow communication between control units.

This means that the verification and diagnosis of these types of systems require special equipment for the measurement of their signals, and for this the oscilloscope is essential.

This course has been developed to provide car repair professionals with all the knowledge that they need to operate this type of equipment effectively.

The main objectives of this course are:

  • To find out about the various types of oscilloscopes and their characteristics
  • To be able to adjust the scale and range of the signals on the oscilloscope
  • To interpret the oscillograms generated by different circuits
  • To provide a diagnostic based on the information provided by this equipment
