pattern representing the input and the output characteristics of the circuit.
6. Adjust the scale and offset of the horizontal and vertical to a desirable waveform
display. The following picture shows a typical example.
7. Apply the Ellipse Method to observe the phase difference between the two channels.
Signal in X-Y Format:
Instruction of the Ellipse Method
Sinθ = A/B or C/D, where θ = phase shift (in degrees) between the two signals.
From the formula above:
θ = _arcsine (A/B) or _arcsine (C/D)
θ must be in the range of (0~π/2) or (3π/2~2π) if the main axis of the ellipse is between I
and III quadrant, . If the main axis is at II and IV quadrant, θ must be in the range of (π/2~π)
or (π~3π/2).
