Roll Mode
In this mode, the waveform scrolls from the right to the left to update the display and
the waveform horizontal position and trigger control are not available. The range of
horizontal scale adjustment is from 200.0 ms to 1000 s.
Note: When Roll mode is enabled,
Delayed Sweep, Protocol Decoding,
Pass/Fail Test, Measurement Range, Waveform Record, To Set the
Persistence Time and To Trigger the Oscilloscope are not available.
Slow Sweep
Another mode similar to Roll mode. When the horizontal time base is set to 200 ms
or slower, the instrument enters “slow sweep” mode in which the instrument first
acquires the data at the left of the trigger point and then waits for trigger event.
After the trigger occur
s, the instrument continues to finish the waveform at the right
of the trigger point. When slow sweep mode is used to observe low frequency
signal, it is recommended that the Channel Coupling is set to “DC”.
