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”.
