Longer recordings

What is exactly the difference between the “oscilloscope” mode and “transient” mode?
The long recordings are possible only in “transient” mode?

In the oscilloscope mode all the data have to acquired to the oscilloscope’s memory before displaying the waveform.
The USB communication used is too slow to transfer the data in “real time”.
The internal data buffer is 4096 samples/channel. This is the maximum amount of continuous data to record.
The buffer must be read to the PC before the next data can be acquired.

In the transient recorder mode the data is immediately transferred to the PC software and displayed on the screen.
The minimum sampling interval is 10ms (100 samples/second) in this mode.
