High Resolution Oscilloscopes for Automotive Diagnostics

Pico ADC-212

The ADC-212 has two features that set it apart from most oscilloscopes (both 'automotive' and 'lab' scopes), the first is resolution and the second is memory depth.

Unlike most digital storage oscilloscopes which typically have 8 bit vertical resolution and poor DC accuracy, the ADC-212 is accurate to 1% and has a 12 bit resolution. This gives a vertical resolution of 4000 'dots' compared to the 100 or 200 of most automotive scopes. As well as its high vertical resolution, the ADC-212 has a large 32,000 reading waveform buffer. This combination makes it possible to capture complex signals and then expand areas of interest to show fine detail (see the library of automotive waveforms for examples of traces captured with the ADC-212)

With the supplied PicoScope software, the ADC-212 can be used as both an oscilloscope and a spectrum analyzer. Whilst applications for the oscilloscope (checking ABS, injector and ignition waveforms) are obvious, the spectrum analyzer can prove a surpisingly useful automotive tool. It is ideal for setting up, testing and repairing car audio and with the addition of a vibration sensor it can help track down worn moving parts such as bearings without dismantling work.
