When you buy a PicoScope Automotive Oscilloscope you get industry-leading performance that is both affordable and easy to use. With the introduction of the PicoScope 4425 and 4225, performance has been upgraded - but the price remains the same!
Pico automotive oscilloscopes are used by more than twenty of the world's leading vehicle manufacturers, and in thousands of workshops to save time and money by making it easier and quicker to diagnose faults.
Which Diagnostics Kit is Right for Me? Compare Kits
The number of dots in the waveform from top to bottom. '12 bits' means 4,096 dots, which is more detail than you can see on the screen all at once. PicoScope stores the extra detail for when you zoom in.
Buffer Memory
The number of dots in the waveform from left to right. If you don't have enough memory then the waveform won't show all the detail in the signal. PicoScope has more than enough memory, so you can zoom in thousands of times and still see a clear display and spot intermittent glitches.
Waveform Buffer
A memory that collects your most recent waveforms. If a waveform disappears off the screen, you can look back through the waveform buffer to find it.
Trigger
This ensures that the scope captures the waveform at the right time and keeps it in a stable position on the screen. PicoScope can set up the trigger automatically, but if you want you can select special trigger modes to catch unusual waveforms that you might otherwise miss.
Bandwidth
For faster signals, more bandwidth gives a more faithful reproduction of the signal shape on the screen. PicoScope has enough bandwidth to display CAN bus and FlexRay signals accurately.
Sampling Rate
Like bandwidth, this is more important for fast signals. A high sampling rate ensures that you catch the high-frequency details of the signal.
