The execute order to obtain the specified data source the waveform data as
following,
:WAVeform:FORMat BYTE
The return format of waveform data is AD single byte mode
:WAVeform:SOURce CHAN1
Set channel 1 as singal source of query waveform data
:WAVeform:POINts 120
set return 120 waveform point
:WAVeform:DATA?
acquire waveform data
