Phillips PM3256 Oscilliscope - How to make Lissajous figures ? - help please

Ah interesting. He's selling CD's with manuals on. I've emailed asked him if he's doing the phillips ones again sometime.

I have found an interesting 'two tone' oscillator here:

I was thinking this would be two sine waves with a guaranteed same trigger / reference point ?

hi,
Yuk!
I would not bother making this 'sine wave' ????? osc.

yuk. Thanks for saving me some solder and verostrip lol. I have come across another interesting design. Its a frequency multiplier. :

I could calculate out the tuned circuit values to get 2 MHz but what value R1 to use ?

I also need a circuit to generate a sine wave using some 2 pin 1MHz ceramic resonators I'm itching to take the soldering iron to. Any ideas ?
