I'm having trouble creating Lissajous to observe the phase shift between two signals
In X-T mode both signals are appeared normally (2 sinus waveforms with the same frequency) but not in X-Y mode...(noise instead of ellipse)
Well, here's what I've done:
I placed the probe attenuation to “x10” on both probes.
I connected the CH1 probe to the input of the circuit, and also the CH2 probe to the output of the circuit.
I had adjusted the vertical scale and offset to display approximately the same amplitude signals on each channel.
Finally I selected X-Y format at Horizontal window.
After that, a square full of noise appears on the computer screen, in contrary with my old analog oscilloscope, where ellipse appears normaly without problems (whith the same signals and ajustments on both channels)
Is that a hardware problem or a software one, and how can I solve it???
