Hello everyone, in this video we will introduce the most commonly used Lissajous measurement method in X-Y mode. First, we will connect two sine wave signals with the same frequency but different phases to Channel 1 and Channel 2. After capturing the waveform, you can see that the phase difference between the two signals is … Read more
