What is the difference between digital real-time (DRT) sampling technology used in the TPS2000 Series and equivalent time sampling (ET) technology used by other manufacturers in the market?

Sample rate determines the highest frequency that can be captured in a single shot. For linear interpolation, the rule of thumb is that the sample rate must be 10 times higher than the highest frequency to be captured for a waveform to be reproduced with good fidelity. The signal complexity will determine the number of samples needed to accurately reproduce the waveform. The TPS2000 Series? market leadership position is driven in large part by its digital real-time sampling technology (1 GS/s and 2 GS/s real-time sample rate) that supports the acquisition of a breadth of waveforms, from repetitive to transient events, up to the full-published bandwidths and to the fastest sweep speeds.

Many competitive digital storage oscilloscope sample rates do not support the actual bandwidth of the oscilloscope, necessitating the use of equivalent-time sampling technology as an alternative. ET technology uses the random overlap of triggered events to recreate a signal, which suffices for truly repetitive signals but fails to capture transient events inherent in most single-shot and non-repetitive signals.
