Hello, again.
I tried with step attenuators and the result is there was difference around 2dB
between 0 degree and 180 degree rotation of horn without attenuator. When I
connected the attenuators to rx and tx paths, the difference raised around
10dB. When I change step of attenuator, I can decr
Hi All,
I am trying to build a firmware for an x300 device that uses the radio block
and the Keep-1-in-N block using UHD 4.4.
For my application I need the Keep-1-in-N block to operate in packet mode, on
packets 2048 samples long.
Before connecting the graph, I try to set the radio block to use
Does anyone know if there is a Spartan-7 based SDR off-the-shelf radio,
currently or in the works? Spartan-6 is only supported by Xilinx ISE tools,
which are hopelessly obsolete by more than 10 years. Plus, there is a
substantial power savings by going from 6 to 7. Thank you.

Thanks, that was very quick and very problem solving :D

Usrp B210 uses AD9361 as transceiver. It has a maximum receiver gain as 76
dB and maximum transmitter gain as 89 dB. Your gain values are too small,
that's why you cannot see anything but noise. Also be careful that AD9361
has a maximum RF input as -15 dBm. But it can genrate and transmit over 10
Hi,
20 and 10dB gain are very low on a B210. See uhd_usrp_probe to see the possible
gain ranges!
Best regards,
Marcus
