Hi all,
I am not an expert on this, but recently speaking to someone a little
more in the know than I...
Marcus is right, also it is apparently possible to pre-calibrate in
advance and save the calibration settings to registers on the AD9361,
thus making the tune time constant.
Just a thought,
Cheers,
Dave

This is probably just a quirk of the way the calibrations cache works in the
AD9361 chip.
The chip isn’t really designed for fast frequency hopping, and when you retune,
internal recalibrations need to happen on the chip, except for small frequency
changes.

Hello
I testing b200mini in receiver mode and found strange result with tune time .
When I start from 100MHz and tune with step 20MHz at freq 200 -> 220 and 120 ->
100 get almost 100 times slowly time then others.
When I start form 101MHz time increase only first pass and then all OK.
Source code and terminal screenshots in attachments.
Thank you
