Roll Mode
In this mode, the waveform scrolls from the right to the left. The adjustable range of
the horizontal time base is from 200.0 ms/div to 1.000 ks/div. The horizontal time
base will be set to 200.0 ms/div automatically when you turn on the “Roll” mode.
Note:
 In this mode, the “To Adjust the Horizontal Position”, “To Turn Delayed
Sweep On/Off”, “Trigger”, “To Specify the Measurement Range”,
“Protocol Decoding”, “Pass/Fail Test”, “Waveform Recording” and “To
Set the Persistence Time” are not available.
 If the delayed sweep function is enabled, when the “Roll” mode is enabled, the
delayed sweep function will be disabled automatically; when the “Y-T” mode is
enabled again, the delayed sweep function will be enabled automatically.
Note: Please pay attention to distinguish the Roll mode from “Slow Sweep Mode”.
