Hello,
I’m acquiring IQ data using bbGetIQUnpacked API.
I was hoping to hopping from one frequency to another, do I have to reconfigure using bb_configure_IQ_center and then reinitiate again?
That takes about couple ms and I’m hoping not having a large gap when switching frequency.
Thanks.Bests,
JingHi Jing,
Yes, you have to reconfigure the receiver between I/Q captures, and yes, with the BB60, there will always be a gap when switching frequencies. I would expect the gap to be in the 10’s of milliseconds.
Unfortunately there is not a way to improve this with the BB60. Our SM200/435 has an I/Q sweep list feature, which allows for preconfigured I/Q frequency/capture_len pairs to allow for very fast switching times, (120us switch times). I can provide more information on that if desired.

How far apart are the frequencies you need to switch between? Maybe you could do it yourself with a “second conversion” in software.
