Hi,
sorry for the late reply. I can't spend all my time hunting down this bug. The issue remains, I know that the lower frequencies (under 1 Ghz) are ok. I will test the width spectrum of frequencies to figure out if all bands are affected.

Re: Sync interface - RX Signal Phase Jumps
Hi,
I'm rather a newbie to BladeRF but I read the issue and I would like to give my idea of what it could be the cause. Maybe I'm wrong, more experienced users could better judge my opinion.
The phase jump could be provoked by the I=0, Q=0 transmitted betweend the burst of bladerf_sync_tx().
If you're transmitting a 100 kHz sine, you probably will have to calibrate the .bin to end with phase =0, otherwise you will always see phasejumps caused by burst truncation (I=0 Q=0).
Cheers
