:WAVeform:DATA?
Command format：

:WAVeform:DATA?
Functional description：

This command is used to read the waveform data from the specified data source.
Return format：

WAVeform:POINts the specified quantity of waveform data. Waveform data source is related to:
WAVeform:SOURce. Data format is related to WAVeform:FORMat. Returned format is conform with
Appendix 2：IEEE 488.2 binary data format.
For example：

The instructions to obtain the waveform data for the specified data source are executed in the following
order.
Obtain screen waveform data flow

:WAVeform:SOURce CHAN1
Set singal source of query waveform data to be queried to channel 1.
:WAVeform:MODE NORMal
Set to read waveform data display on the screen.
:WAVeform:FORMat BYTE
Return format of waveform data is AD single byte mode.
:WAVeform:DATA?
Acquire waveform data.
Obtain internal waveform data flow, this flow can only valid in stop status.

:WAVeform:SOURce CHAN1
Set singal source of query waveform data to be queried to channel 1.
:WAVeform:MODE RAW
Set to read interal storage waveform data.
:WAVeform:FORMat BYTE
Return format of waveform data is AD single byte mode.
:WAVeform:POINts 5000
Reading internal waveform point is 5000.
Cycle reading internal waveform data.
{
:WAVeform:DATA?
Acquire a piece of waveform data in internal storage.
:WAVeform:START?
Start position of waveform data reading, -1 represents the last point.
}
Explanation: when reading internal data in batch, the read back data of each time is only the data of an area
in the memory, and the waveform data between two adjacent pieces is continuous. Each piece of data
conforms to Appendix 2: IEEE 488.2 binary data format.
