Hello,
I have a small issue. I want to use the prebuilt fft block to check the
behavior of CORDIC block in a testbench. It returned an error:
ERROR: [VRFC 10-2063] Module not found while processing module
instance
[/home/kei/rfnoc/src/uhd-fpga/usrp3/lib/rfnoc/noc_block_fft.v:237]
Obviously
The AGC is by default in manual mode when using GNU Radio.
GNU Radio doesn't expose (gr-uhd) the AGC function Marcus referred to. If
you want to use AGC in GNU Radio, you'll have to extend the source code a
bit.

Dear Robin,
Thanks for the quick reply. Although the 180-degree ambiguity is already good
to know, what we are observing is really some rotation in the IQ plane (not
just an ambiguity).
Does the LO lock happens fast? Or should I wait for some time after launching
my GNURadio script
The Analog Devices AD9361 RF integrated transceiver in the B205mini has a
divide-by-2 PLL inside when using an external reference input, so there
will always be a 180 degree phase ambiguity.

Dear all,
Im having a problem synchronizing two USRP-B205 mini.
The setup is as follows: I use one USRP as a transmitter, the other as a
receiver, and they are connected by cable. The ref input of both USRPs is
connected to a 10MHz output (also tried with PPS output) of an Octoclock.
