Lissajous Figures

Setup:
1. Connect the trigger output from Pasco Scientific to Ext. trigger on Lan Scope.
2. Connect the ground output from Pasco Scientific to Ext. Ground on Lan Scope. 
3. Connect channel 1 output from Pasco Scientific to 0.01 micro farad capacitor connected to positive channel Y1. 
4. Connect channel 2 output from Pasco Scientific to 0.01 micro farad capacitor connected to positive channel X1. 
5. Connect main ground from Pasco Scientific to Y1 negative. 
6. On Lan Scope jumper X ground to Y1 ground. 
7. Adjust the frequencies of the Pasco generator so that the gains and phases are approx. equal. 
8. Adjust the C.R.O. gain control so that a round circle is formed. 

Method:
1. Set X and Y to the same frequency (Channel #1a and #1a) 
2. Observe the circular pattern produced by two waves of the same frequency 
3. Keeping the Y input fixed at 1(a) move the x input to different frequency multiples. 
4. Observe the change in the Lissajous figures
