Hello magintd,
I can clarify. The bbr file is a flat recording of sweeps only (frequency domain ‘bins’). The IQ data is not recorded in this file. The sweeps are stored as min/max arrays. If the avg detector is enabled, min/max should equal the same values. I will attach a basic bbr parser so you can see the layout and how we parse the files in our software.
If you are looking to get IQ data, then we do have another recording feature in zero-span that records IQ data. If you are looking for the ultimate flexibility, you could grab IQ data directly from the device with our APIs.
Let me know if you have additional questions.
Regards,
A.J.
