CHANnel<m>:DATA:POINts
<Points>
As a setting, the command selects a range of samples. As a query, it returns the num-
ber of samples for the selected range. To get correct results with settings MAX and
DMAX, the acquisition must not run when the command is used. To acquire consistent
and valid data, use the SINGle command before. Do not cancel a running acquisition
with STOP because the waveform data might be incomplete or incorrect.
Suffix:

Selects the input channel (1, 2).a
Setting parameters:
<Points>
DEFault | MAXimum | DMAXimum
Sets the range for the queries.
DEFault
Waveform samples displayed on the screen.
MAXimum
Range is the complete memory.
Note:
Reading the complete memory is only possible in STOP
mode, and if maximum sample rate is set (
DMAXimum (Display Maximum)
Number of samples in the current waveform record.
Return values:
<Points>
Number of data points in the selected range (samples). The
number of data points is depending on the timebase and chan-
nel settings.
Example:
The instrument recorded 10000 samples. 6000 of these samples
apply to the screen. To create the display points, every 6 points
are combined to a MIN-MAX pair, and 1000 of these data pairs
are displayed on the screen. For DEFault, 2000 is returned
(1000 data pairs). DMAX returns 6000, and MAX 10000 (the
complete memory).
