Abstract

A test and measurement instrument includes a memory configured to store a digitized signal, a display configured to display the digitized signal, a mark interface configured to generate a mark creation signal, a processor coupled to the memory, the display, and the mark interface. The processor is configured to identify a feature of the digitized signal and create a mark indicating the feature and the digitized signal in response to the mark creation signal.
