Detail Contains the waveform amplitude and time of each
point (4k/1M/2M) relative to the trigger point.
Fast Only contains the waveform amplitude data for each
point (4k/1M/2M).
Waveform type CH1, 2

Storage location Internal
memory
The oscilloscope’s internal memory,
which can hold 15 waveforms.
External USB Flash
drive
A USB ash drive (FAT or FAT32 format) can hold
practically an unlimited number of waveforms.
Ref A, B Two reference waveforms are used as a buffer to
recall a waveform in the display. You have to save a
waveform into internal memory or to USB, then copy
the waveform into the reference waveform slot (A or B),
and then recall the reference waveform into the display.

Memory Depth
The memory depth is limited to 1 M points when both channels are activated or
2M points when only a single channel is activated. The signal must be triggered
/stopped to have access to the full memory depth. Therefore when a signal is
saved the waveform will be automatically stopped if it is not manually triggered /
stopped rst.
There are a number of conditions when all of the available memory is not utilized
due to a limited number of different sample rates. This can be caused by an
un-triggered signal, or a time/div setting that is too fast to display all the points
on screen.
