Chapter 4 To Set the Sample System
4-4 MSO5000 User's Guide
Note:

In XY mode, CH1 and CH2 are forced to be enabled; CH3 and CH4 are forced to
be disabled. 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" , "Vector display" , "Scale" , "Protocol Decoding" ,
"Acquisition Mode" , "Pass/Fail Test" , "Waveform Recording &
Playing" , "Digital Channel" , and "To Set the Persistence Time" .
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 time base 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".
