Digital sampling oscilloscopes
The maximum sampling rate of digital storage oscilloscopes has
increased enormously over the years, from a few hundred
kilosamples per second to 5Gs/s, which at the time of writing
currently represents the state of the art. This performance enables
a user to capture a waveform with significant energy at frequency
components up to 1GHz, on a single shot basis, or a sinewave at
the full 1GHz bandwidth of the input circuitry on an
oscilloscope, without using equivalent time sampling and
therefore with no danger of a misleading display due to aliasing.
A good example ...
