RIGOL
Note:
In XY mode, CH1 and CH2 are forced to be enabled. The maximum sample rate
in XY mode is 2 GSa/s. Generally, a 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 a longer waveform
(refer to the introduction in "Memory Depth"). Therefore, during the
measurement, reducing the sample rate properly can achieve better display
effect of Lissajous figure.
The following functions are disabled in XY mode:
"Delayed Sweep", "To Select the Display Type", "Scale", "Protocol
Decoding", "Pass/Fail Test", "Waveform Recording & Playing", and
"Digital Channel".

ROLL Mode

In this mode, the waveform scrolls from right to left to update the display. The
available range of the horizontal scale is from 200 ms to 1 ks. Press More → Auto
ROLL to select "ON". The system automatically enters the ROLL mode, and there is
no slow sweep.
Note:
If the current delayed sweep is enabled, then when you enable the ROLL mode,
the delayed sweep is disabled automatically. When you re-enable the "YT" mode,
the delayed sweep will be re-enabled.
The following functions cannot be set in ROLL mode:
"To Adjust the Horizontal Position" (available when the oscilloscope is in
"Stop" operating status), "Delayed Sweep", "To Trigger the Oscilloscope",
"Protocol Decoding", "Pass/Fail Test", "Waveform Recording &
Playing", and "To Set the Persistence Time".
Slow Sweep
It is similar to the ROLL mode. In YT mode, when the horizontal timebase is set to
200 ms/div or smaller, the instrument enters the "slow sweep" mode in which the
instrument first acquires the data at the left of the trigger point and then waits for
a trigger event. After the trigger occurs, the instrument continues to finish the
waveform at the right of the trigger point. When observing the low-frequency
signal in the slow sweep mode, it is recommended that you set "Channel
Coupling" to "DC".
