Hello Chahatb,
I think you misunderstand what signals you have available in your (blue) Dynamic Data wire.
- You have one "waveform" in that blue wire.
- Then you connect it two times to a VI (WDT Index Channel DB.vi) that expects an array of waveforms at its inputs.
This will "make LabVIEW think" that you want to convert your single waveform to a waveform array contains exactly one waveform inside it.
- Afterwards you take index 1 and 2 from that array.
Since arrays are zero indexed this is the same as trying to retrieve the second and the third waveform in the array.
This will not give you back meaningfull data, because you do not have a second and a third waveform in that array. (it only contains a waveform at index 0)
In attachment I have reduced your original posted code and only kept the code you wrote that relates to the complex data.
This is done to illustrate what I explained above and why it doesn't work.
Kind Regards,

If someone helped you, let them know. Mark as solved and/or give a kudo. 😉
