4. Observe the measurement result shown in the figure above. According to the

measurement schematic diagram of the phase deviation (as shown in Figure

3-2

), A/B (C/D) = 1. Thus, the phase deviation angle θ=±arcsin1=90°.

Note:

 The maximum sample rate of X-Y mode is 1.0 GSa/s. Generally, longer sample

waveform can ensure better display effect of Lissajous figure. But due to the

limitation of the memory depth, you have to reduce the waveform sample rate

to acquire longer waveform (refer to the introduction in “Memory Depth”).

Therefore, during the measurement, reducing the sample rate properly can

acquire better display effect of Lissajous figure.

 When X-Y mode is enabled, “Delayed Sweep” will be disabled automatically.

 The following functions are not available in X-Y mode:

“Auto Measurement”, “Math Operation”, “Reference Waveform”,

“Delayed Sweep”, “Vectors”, “horizontal position”, “To Trigger the

Oscilloscope”, “Protocol Decoding”, “Acquisition Mode”, “Pass/Fail

Test”, “Waveform Record” and “Digital Channel

”.

Method 2: Use the shortcut measurement function

Please refer to “Phase 1 →2 ”, “Phase 1 →2 ”, “Phase 1 →2 ” and “Phase

→2 ” measurement functions of “Delay and Phase”.
