Why Do We Adjust the Time Base?


  • The example display view we see on the left is a 10Hz A.C. signal, and a 10kHz signal being viewed on the same Time Base (or horizontal scale).
  • Because we are viewing on a scale that allows us to see the 10Hz signal clearly, the 10kHz signal appears to be a collection of vertical lines in very close proximity of each other.
  • So it is possible to measure the period of the 10Hz signal but not the 10kHz signal.

  • Because we are viewing on a scale that allows us to see the 10kHz signal clearly, the 10Hz signal appears to be a curved line trailing off the edge of the display.
