:WAVeform:DATA?

Syntax
:WAVeform:DATA?
Description
Read the waveform data.
Explanation
Procedures of the screen waveform data reading:

1)
2)
3)
Procedures of the internal memory waveform data reading:

1)
2)
3)
4)
Return The data returned contains 2 parts: the TMC data description header and the

Format waveform data. The format of the TMC data description header is #900000dddd
which is followed the waveform data. Wherein, dddd denotes the number of bytes of
the effective waveform data. For example, as shown in the figure below,
#9000015865 is the TMC data description header. Wherein, 15865 denotes that
there are 15 865 bytes of effective data and it is followed by the waveform data read.
The return format of the data is ASCii.
When the return format of the waveform data is ASCii (refer to :WAVeform:FORMat),

the query returns the actual voltage of each point on the screen in scientific notation.
When reading the waveform data in the internal memory, the data returned each

time may be the data in one area in the internal memory (you can set the start point
and stop point using
data returned contains the TMC data description header and the waveform data from
two adjacent parts are continuous.
