Hi,
I am trying to calculate the link budget for USRP N310.
Suppose I want a SNR of 20dB,
the signal bandwidth is 10MHz,
the thermal noise floor is -103.9dm.
Receiver noise figure is 5.8dB (N310 datasheet 5.8dB @1.8GHz)
Rx Antenna Gain 6dBi
Path loss: 120dB
Tx Antenna Gain 6dBi
RF cable Loss (RX+
Hi everyone,
I follow the instruction in the following website in order to add new IP to my
X310.

At the last stage in the website, in order to build the bin file that burn to
the FPGA, they use the make.p
Hello Robin,
Thanks for the reply. We quickly tried your suggestion, and it seems to
work fine!
We first thought it was impossible to have 2 living streamers at the same
time, because of the next comment in uhd/device.hpp
Note: There can always only be one streamer. When calling get_tx_stream()
The Receiver Noise figure should include sampling noise and ADC ENOB.
Is that a free space path loss? You don't have any design margin for
fades/blockages etc, so an External LNA might be a good idea. 3.6 dB
NF isn't particularly low for a LNA, but it will help.

I'm not a Boeing Employee, but I came across this and though some
folks on the mailing list might be interested.

Thank you for the response. 3.6dB NF is not impressive however I was
considering a wideband LNA as an once-for-all solution for the entire
frequency range 50-6000MHz of N310.
Let me re-phrase the question in two different ways:
1) What is the minimal discernible signal (MDS) at the input of the N

On a side note, the combination of wideband LNA's in front of wideband
radios is generally something to be careful of, as strong signals out
of band can cause problems. Bandpass filtering in front of LNA's can
be a very good idea to think about.

Hello,
As I wanted a statically linked .lib I downloaded the source, but I've
had a lot of trouble trying to build the library. I'm using VS 2017,
and the latest Boost version, and libuhd. I compiled Boost for static
linkage and the complete libuhd system. Then cloned the uhd and tried

Hi all,
We have two pieces of E313,the difference of them is one of them insert sg1
imges and another insert sg3 image.
When we take DC power supply(12V) for e313,the sg1's e313 would auto
start,but for the sg3's e313,we must press power button,then e313 power on.
Is it normal?How could make auto
