andrewcleggParticipantHi all–
I’ve written a script to import .bbr data into python. All works well. I just have a dumb question — why are there two copies of each spectrum sweep in the binary file? In the playback_toolbar.cpp code on github (lines 67 & 68), the two copies are referred to as min and max. But in my mode of data collection, the two sets are always exactly the same. Under what circumstances are they different?
Thanks!
Andy
AndrewModeratorHi Andy,
The two arrays would be unique using the min/max detector with most rbw/vbw/sweep time settings. They are always the same when using the average detector. The min values can probably be discarded for most purposes.
Let me know if you have further questions.
Regards,
A.J.
andrewcleggParticipantThanks A.J. That’s helpful. I never use the min/max detector, so that’s why I didn’t encounter any differences.
