Random sampling is a sampling oscilloscope technique that allows viewing of the pre-trigger regions of the waveform, as well as the actual trigger event and after the trigger event.
In some applications, it eliminates the need for a delay line in the vertical signal path, thereby avoiding the signal integrity problems of delay lines.
Random sampling is provided by the 3T2 and 7T11.
Random sampling is described by George Frye in US Patent 3,611,003.
