2.4Sampling modes
7
PicoScope 2000 series PC Oscilloscopes can 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 a preset number of data points has been sampled. This
is called block mode. At very low sampling rates, you may want to switch to streaming mode. This allows accurately timed data to be transferred back to the PC in short blocks, without gaps. Real time continuous mode is also provided for use at low sampling rates, when immediate data transfer without gaps is required but timing accuracy is not critical.
