Unknown Issue with Hitachi V-1050F Oscilloscope
<< < (3/3)
Wallace Gasiewicz:
Compensation adjustments are little screws on the oscilloscope probes, if you are using probes for input.       

The input lines to the scope must match, must be the same length and characteristics, otherwise phase shift will result. The higher the freq the more this is obvious on the screen.     
If you are using the stereo audio jack to supply the signal, is is probably out of phase at that point.  Use the same channel, exactly the same source for both signal connections.     

The circle you were expecting is caused by two sine waves of the exact same frequency exactly 90 degrees out of phase. As you have discovered.
