Return values:
<Data> List of values according to the format settings - the voltages of
recorded waveform samples.
Example:
FORM ASC
CHAN1:DATA?
-0.125000,-0.123016,-0.123016,-0.123016,
-0.123016,-0.123016,...
Example: See
Chapter 15.2.1.3, "Reading Waveform Data in Real For-
mat"
, on page 243 and Chapter 15.2.1.4, "Reading Waveform
Data in Unsigned Integer Format"
, on page 243
Usage: Query only
CHANnel<m>:DATA:HEADer?
Returns information on the channel waveform. For envelope waveforms, use the
CHANnel<m>:DATA:ENVelope:HEADer? command.
Table 15-1: Header data
Position Meaning Example
1 XStart in s -9.477E-008 = - 94,77 ns
2 XStop in s 9.477E-008 = 94,77 ns
3 Record length of the waveform in Samples 120000
4 Number of values per sample interval, usually 1. 1
Suffix:
<m>
.
1..4
Selects the input channel. The number of channels depends on
the instrument.
Parameters:
<DataHeader> Comma-separated value list
Example: -9.477E-008,9.477E-008,120000,1
Usage: Query only
CHANnel<m>:DATA:POINts <PointSelection>
As a setting, the command selects a range of samples that will be returned with
CHANnel<m>:DATA? and CHANnel<m>:DATA:ENVelope?. As a query, it returns the
number of returned samples for the selected range.
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.
