Waveform Commands 32
Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 875
:WAVeform:DATA?
Query :WAVeform:DATA? [<start>[,<size>]]
The :WAVeform:DATA? query outputs waveform data to the computer over
the remote interface. The data is copied from a waveform memory,
function, channel, or digital channel previously specified with the
:WAVeform:SOURce command.
The preamble queries, such as :WAVeform:XINCrement, can be used to
determine the vertical scaling, the horizontal scaling, and so on.
<start> An integer value which is the starting point in the source memory which
is the first waveform point to transfer.
<size> An integer value which is the number of points in the source memory to
transfer. If the size specified is greater than the amount of available data
then the size is adjusted to be the maximum available memory depth
minus the <start> value.
Streaming Off The returned waveform data response depends upon the setting of the
:WAVeform:STReaming command. When the data format is BYTE and
streaming is off, the number of waveform points must be less than
1,000,000,000 or an error occurs and only 999,999,999 bytes of data are
sent. When the data format is WORD and streaming is off, the number of
waveform points must be less than 500,000,000 or an error occurs and
only 499,999,999 words of data are sent.
The returned waveform data in response to the :WAVeform:DATA? query is
in the following order.
NOTE
The data's returned response depends upon the setting of the :WAVeform:STReaming
command. See "Streaming Off" on page 875see " or "Streaming On" on page 876 for more
detail.
NOTE
If the waveform data is ASCII formatted, then waveform data is separated by commas.
