DATa:STOP
This command sets or queries the last data point that will be transferred when
using the CURVe? query. This command allows for the transfer of partial
waveforms to
the controller.
Changes to the record length value are not automatically reflected in the data:stop
value. As re
cord length is varied, the data:stop value must be explicitly changed
to ensure the entire record is transmitted. In other words, curve results will not
automatically and correctly reflect increases in record length if the distance from
data:start to data:stop stays smaller than the increased record length.
NOTE. When using the CURVe command, DATa:STOP is ignored and
WFMInpre:NR_Pt is used.

Arguments
<NR1> is the last data point that will be transferred, which ranges from 1 to
the record length. If
<NR1> is greater than the record length, then data will be
transferred up to the record length. If both DATa:STARt and DATa:STOP are
greater than the record length, the last data point in the record is returned.
DATa:STARt and D ATa:STOP are order independent. When DATa:STOP is less
than DATa:STARt, the values will be swapped internally for the CURVE? query.
If you always want to transfer comple te waveforms, set DATa:STARt to 1 and
DATa:STOP to the maximum record length, or larger.
Examples
DATA:STOP 15000 specifies that the waveform transfer w ill stop at data point
15000.
DATA:STOP? might return :DATA:STOP 14900, indicating that 14900 is the last
waveform data point that will be transferred.
