Technician Handbook ! 673 Electronic & Computer Controlled Systems Capturing Waveforms If it’s necessary to see exactly what’s happening in a signal that is not repeating, many oscilloscopes offer a capture feature . When a waveform is captured, a designated time period of signal is recorded in memory so it can be played back and examined in detail. The specifics of how this feature operates vary with different model oscilloscopes. In general, however, the more memory available for recording, the longer the time period that can be captured and the greater quantity of captures that can be kept in memory at one time.
Two of the advantages of PC oscilloscopes are a large memory and removable storage media for saving captures. 40 Technical Training
