Depending on the current settings, the memory can contains more data samples than
the screen is able to display. In this case, you can decide which data will be saved:
samples stored in the memory or only the displayed samples.
Note:
The sample range can only be changed in STOP mode. If the acquisition is run-
ning, DEF is always used automatically. If the acquisition has been stopped, data can
be read from the memory, and all settings are available.

The command affects all channels, and the suffix is irrelevant.
Setting parameters:
<PointSelection>
DEFault | MAXimum | DMAXimum
Sets the range for data queries.
DEFault
Waveform points that are visible on the screen. At maximum
waveform rate, the instrument stores more samples than visible
on the screen, and DEF returns less values than acquired.
MAXimum
All waveform samples that are stored in the memory. Only avail-
able if acquisition is stopped.
DMAXimum
Display maximum: Waveform samples stored in the current
waveform record but only for the displayed time range. At maxi-
mum waveform rate, the instrument stores more samples than
visible on the screen, and DMAX returns more values than DEF.
Only available if acquisition is stopped.
