Introduction to
The WAVeform subsystem is used to transfer data to a controller from the
:WAVeform oscilloscope waveform memories. The queries in this subsystem will only

operate when the channel selected by :WAVeform:SOURce is on.
Waveform Data and Preamble
The waveform record is actually contained in two portions: the preamble
and waveform data. The waveform record must be read from the
oscilloscope by the controller using two separate commands,
:WAVeform:DATA (see
page
in the specified source. The preamble contains the information for
interpreting the waveform data, which includes the number of points
acquired, the format of acquired data, and the type of acquired data. The
preamble also contains the X and Y increments, origins, and references for
the acquired data, so that word and byte data can be translated to time
and voltage values.
