Position Meaning Example
3 Record length of the waveform in Samples 200000
4 Number of values per sample interval. For most
waveforms, the result is 1. For peak detect and
envelope waveforms, it is 2. If the number is 2, the
number of returned values is twice the number of
samples (record length).
1
Suffix:
<ch>
.
1 to 8, depending on instrument model. Index of the analog
channel.
<wf> 1, can be omitted
Example:
CHAN1:WAV1:DATA:HEAD?
-9.477E-008,9.477E-008,200000,1
Usage: Query only
Asynchronous command
CHANnel<ch>[:WAVeform<wf>]:DATA[:VALues]? [<Offset>],[<Length>]
Returns the data of the channel waveform points for transmission from the instrument
to the controlling computer. The data can be used in MATLAB, for example.
Without parameters, the complete waveform is retrieved. Using the offset and length
parameters, data can be retrieved in smaller portions, which makes the command
faster. If you send only one parameter, it is interpreted as offset, and the data is
retrieved from offset to the end of the waveform.
To set the export format, use FORMat[:DATA] on page 439.
Suffix:
<ch>
.
1 to 8, depending on instrument model. Index of the analog
channel.
<wf> 1, can be omitted
Query parameters:
<Offset> Number of offset waveform samples to be skipped.
Range: 0 to m. Limit: n + m <= record length
<Length> Number of waveform points to be retrieved.
Range: 1 to n. Limit: n + m <= record length
Return values:
<Data> List of values according to the format and content settings.
Example: Retrieve the complete channel 1 waveform, only Y-values:
