  • Page 20: Rapid Block Mode

    In normal block mode, the PicoScope 5000 series scopes collect one waveform at a time. You start the the device running, wait until all samples are collected by the device, and then download the data to the PC or start another run. There is a time overhead of tens of milliseconds associated with starting a run, causing a gap between waveforms.
