Introduction to
:WAVeform
Commands
The WAVeform subsystem is used to transfer data to a controller from the
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 717) and :WAVeform:PREamble (see page 724).
The waveform data is the actual data acquired for each point 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.
