8 PicoScope 4000 Series Automotive Oscilloscope User's Manual 3 Advanced features 3.1 Sampling modes 9 PicoScope 4000 Series Automotive Oscilloscopes run in various sampling modes. At high sampling rates, the oscilloscope collects data much faster than a PC can read it. To compensate for this, the oscilloscope stores a block of data in an internal memory buffer, delaying transfer to the PC until the required number of data points have been 8 sampled. This is called block mode. At very low sampl

Glossary 9 4 Glossary AC/DC control. Each channel can be set to either AC coupling or DC coupling. With DC coupling, the voltage displayed on the screen is equal to the true voltage of the signal with respect to ground. With AC coupling, any DC component of the signal is filtered out, leaving only the variations in the signal (the AC component). Aliasing. Like all digital scopes, the PicoScope 4000 Series cannot reliably capture signals with a frequency higher than half the scope's maximum s
