Contains the waveform amplitude and
time of each point (4k/1M/2M)
relative to the trigger point.
Only contains the waveform
amplitude data for each point
(4k/1M/2M).
Math operation result (page 62)
The oscilloscope’s internal memory,
which can hold 15 waveforms.
A USB flash drive (FAT or FAT32
format) can hold practically an
unlimited number of waveforms.
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.
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 first.
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.
