Inquiry: Oscilloscope

Purpose: To learn how to use an oscilloscope, and to use it to observe signals and to make frequency measurements.

Procedure:

Connect a signal generator to both the vertical and horizontal inputs. Set the vertical to 400 hz on the oscilloscope and try to generate the below Lissajous figures. For each ratio determine the horizontal frequency needed to generate that figure and record in your notebook.

Inquiry Questions:

  1. If a 123 Hz signal was sent to the horizontal input of an oscilloscope and the 5:6 lissajou pattern above was seen, what is the vertical signal in Hz?

  2. Update your Google Waves Program to create Lissajou patterns!
