Sampling Methods

Last Modified: December 18, 2020

Depending on the device, you can select different sampling methods from the Instrument Settings window of an oscilloscope:
  • Real time—Gathers all the samples for a waveform in one acquisition with one trigger event.
  • RIS—Random Interleaved Sampling (RIS) achieves a higher synthetic sample rate by combining several triggered waveforms.

    RIS is not supported on all oscilloscopes. You can select RIS only with supported devices. Refer to your device's documentation to determine whether or not it supports RIS.
