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.
Suffix:
<m>
.
1..4
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.
*RST: DEFault
Return values:
<Points> Number of data points in the selected range.
Default unit: Samples
Example:
CHAN:DATA:POIN DEF
CHAN:DATA:POIN?;:CHAN2:DATA:POIN?
Returned values: 10416;10416
CHAN:DATA:POIN DMAX
CHAN:DATA:POIN?;:CHAN2:DATA:POIN?
Returned values: 124992;124992
CHAN:DATA:POIN MAX
CHAN:DATA:POIN?;:CHAN2:DATA:POIN?
Returned values: 4194302;4194302
Example: See
Chapter 15.2.1.3, "Reading Waveform Data in Real For-
mat"
, on page 243
CHANnel<m>:DATA:ENVelope?
Returns the data of the envelope. The envelope consists of two waveforms. The wave-
forms data can be used in MATLAB, for example.
Use this command only for envelope waveforms. For other channel waveforms use
CHANnel<m>:DATA?.
