//store data in this path and filename
EXPort:WAVeform:RAW ON
//export as raw ADC integer values (saves memory) --> data needs to be converted later
EXPort:WAVeform:INCXvalues OFF
//disable time values in data file. Time can be constructed from the header file
CHANnel1:WAV1:HISTory:STATe ON //switch to history view
EXPort:WAVeform:DLOGging ON //enable data logging & history
EXPort:WAVeform:TIMestamps ON //enable relative time stamp for each acq.
CHANnel1:WAV1:HISTory:STARt -99 //oldest waveform of n acq. has index =(-1)*(n-1)

//2 files are created: header file *.bin and waveform data file *.Wfm.bin

//Sorting out the binary waveform data is more complex and require additional coding

//e.g. 'int8' for MATLAB
