    The Origins of Delayed Timings on Oscilloscopes

    element14 Presents  |  Bald Engineer: James Lewis' VCP Profile |  Workbench Wednesdays



    Almost everyone uses a digital oscilloscope’s zoom features. However, did you know that 40-year-old analog oscilloscopes can do something similar? Delayed time bases on analog scopes sweep twice so that the user can see a slow and fast sweep. In this video, see where “zoom” came from and how engineers accomplished the same measurement back in the day.


    Minor correction about the old scope that I showed. I kept calling it a “7704.” The 7704 is from the early 1970s. The unit I have is actually the updated model the 7704A.
