If the AC source MUST be floating. Connect the scope ground to the junction of diac and R2 or R3 depending which you are using. Connect the Y channel (voltage) to the top of the diac and the X channel (current) to the AC GND. Invert the X channel to get the correct polarities. This will display the IV curve on the scope.
and i last what are the proper connection if ths ac source is no floating ?Yup.
Yes when i run the experiment i upload an image maybe... This thread is interesting and informative. If it is not too much trouble, could the original poster give us a screen shot or diagram of the resulting scope image?
If the scope and the AC source are both grounded (scopes are usually grounded) then you can't do it by simply connecting the scope probes.and i last what are the proper connection if ths ac source is no floating ?
thank you again
Those connections are as I indicated in post #2 and will work fine as long as the AC source is not grounded.the manual of this expirement write "

The oscilloscope is connected as in my drawings in the simulator. Where are the oscilloscopes? It would be interesting to compare!With those connections CH1 should be X and CH2 should be Y on the 'scope display.
