Hi Jared,
The same limitation would happen with the BB60C. Our implementation requires the channels fit within the span. If you weren’t using the device in real-time mode, I would simply suggest increasing your span to 300kHz. Otherwise we would need to change our implementation to integrate partial channels when available (non-ideal) or allow custom adjacent channel sizes (ideal). It’s on the TODO list and something I’ve been wanting to add for a while (individually selectable channel bandwidths) I’ll see if I can’t get it pushed up the list.
I apologize for the inconvenience.
Regards,
A.J.
