Hi Stephan,
Try moving the GPSDO power from the J509 connector to the J102 connector on
the N200 motherboard. J102 is 6V AUX power and does not sag when running.
The provided cable is a little short, so you will have to get creative.
Give that a try and let us know if it solves the problem.
Rega
Marcus,
Thanks for you email. The following works:
rfnoc_rx_to_file --args="type=x300" --nsamps=65536 --block-id=FFT_0
--block-args="spp=256" --rate=200e6 --freq=2400e6
It is curious that the "spp=256" is necessary given that this is the
default and a call to "get_args" will return 256. But, if

Hello at all, it is my first time using a mailing list so I hope I have done
everything right.
Is it possible to use the "connection" setup described in

No there is not.
Power is computed by squaring the real and imaginary components of the signal
and adding and averaging over a suitable time interval.
Phase is always measured relative to some other signal. So measuring at the
antenna port makes no sense. Unless you’re talking about measurin
Thank you very much for your answer, it has been really useful.
Another question I wanted to ask is if it is possible to measure the RF
power and phase at the receiver port before the signal goes to the ADC.
If so, how can I obtain that RF information? Is there a way to show it
in GNU radio or
Hi,
No, it's not. Each of your UBX-160 has one Rx chain.
BTW somehow it is common confusion that Tx/Rx and Rx2 ports can be used
to receive signals simultaneously. I have to explain this even to people
with professor degree in electronic engineering, that behind these ports
there is one Rx chain
Hi again,
Thank you very much for your answer. I have bought two daughter boards
UBX-160, is that enough to have 4 receivers at the same time?
Thank you!
Best regards,

Hi all,
My name is Maria and I have the USRP X-310, which has 4 ports, 2 Tx/Rx
and 2 Rx. I would like to ask if you can use the 4 ports as receivers at
the same time.
Thank you very much in advance!
