axis and the circle to the origin of the coordinates are approximately equal. Thus,
the phase deviation angle
Note:
In Y-T mode, the oscilloscope could use arbitrary sample rate (within the

guaranteed range) to capture waveform. The maximum sample rate of Y-T
mode is 2.5 GSa/s. Generally, reducing the sample rate properly could get a
Lissajous figure with relatively better display effect.
When X-Y mode is turned on, "Delayed Sweep" will be turned off

automatically.
The following functions are not available in X-Y mode:

"Horizontal Position", "Delayed Sweep", "Acquisition Mode", "To
Trigger the Oscilloscope", "Math Operation", "One-key Measurement",
"Measurement Range", "Protocol Decoding", "Reference Waveform",
"Pass/Fail Test", "Waveform Recording", "Vectors Display" and "To Set
the Persistence Time".
Method 2: Use the shortcut measurement function
Please measure the phase deviation between the input waveforms of CH1 and CH2
by referring to the phase deviation measurement function in "Delay and Phase" on
page 6-19.
