Hi Ian,
To answer your questions:
- The absolute times after run are around the 6 second mark as expected,
just with some additional 10s to 100s of microseconds that appears random
on each B210.
- All of the B210s are powered by the 5.9V 4.0A adapter they came with.
Now some good news: I think I'
This is a particularly curious problem.
The offset between B210’s of the “time after run” values after sample capture
has completed is very hard to explain…certainly from a hardware only
perspective.
What are the absolute time values reported? Are they at least approximately 5-6
seconds as you m
Thanks Marcus. I've done a little more debugging with a simple C++ example
and the B210, and discovered that calling get_rx_stream() seems to be
slightly changing the device time by random amounts when 2 channels are
used. It doesn't matter if I actually issue a stream command or collect any
data.

Marcus,
Thanks for the suggestion. I added set_subdev_spec('A:A A:B') for the
2 channel case, but the results are the same.
I also tried this code with a pair of X310s receiving. The results are
somewhat similar:
- Channel 0 (A:0)

- Channel 0 (A:0) across 2 devices: no delay
- Channel 1 (B:0) across 2 devices: no

Hi,
I'm trying to synchronize multiple B210s to receive data at the same time.

I've had success with 1 RX channel across 2 B210s, but something seems
