Hi All,
Last year I did was working on a uni paper looking at developing a generic
software-defined radar transmitter using GNU Radio as part of a university
submission. The gnu radio list was instrumental to me learning about
Software Defined Radio, getting my USRP N210 up and running and helpin
Hey David,
Thanks very much, your inputs be a great help!

Apologies that copy paste formatting was attrocious..! Data attached in
file.
P.S. earlier I meant to say f1 = 4MHz and f2 = 5 MHz
In the attached data
m1 = 2*f1-f2
m2 = f1
m3 = f2
m4 = 2*f2-f1
thx!

I assume by baseband filter, that you mean this is a digital filter that
applies what I send from the CPU to the USRP..

Hi All,
I'm looking at the parts of the XCVR2450 trying to do theoretical gain /
noise calcs.
My first question is... has anyone else done these? Do my numbers seem
reasonable?
Secondly.. I don't know what gain the AD8132 has.. it seems to offer G
=1,2,5,10 according to page 15...

I have a few queries regarding some of the options for improving the
performance of the XCVR2450 + N210.
1) The N210 can offer 50MSPS with 8 bit I&Q samples or 25MSPS with 16bit
1&Q.
If using 16 bit I &Q samples, I'd just leave the UHD input block with
"Complex int 16".
How do I implement 8 bit I&
Hi All,
I'm looking at how suitable USRPs are as potential transmitters.
This is for a uni project.. I'm looking for avenues (heck you might even
say simple exercises) of aspects I can investigate for the N210 + XCVR2450.
With so much info available for the individual hardware components

Hi Josh,
Sorry for the belated reply!
Yes it says 6GHz on the uhd_usrp_probe but i was just surprised given that
the website said its limit was 5.9GHz.

I'm doing a bunch of testing on the USRP N210 with the XCVR2450.
In particular i'm looking at areas where there is odd behaviour at extremes
etc and at trying to put it in context.
One thing i've started to notice is that as I step up the uhd gain the
readings I get on the spectrum analyser do not
Ah that makes sense!
Thanks guys!

Hi All,
I've toyed around a fair bit with the UHD_sink parameters for the target
Centre Frequency, and in particular using the request command to set the
centre freq and the LO Offset.
But i can't seem to see any impact from the LO offset!
E.g.
IF = 5 MHz
Target RF = 100MHz
LO thus would equal 95
Hi,
This is a two part question
1) What are the XCVR2450 bandwidth options?
I've looked at the website and discussion list threads on the matter and
seen different answers on what the the bandwidth options are for the
XCVR2450 daughterboard.
The spec sheets seem to indicate different answers too.
..
As opposed to chopping a cosine with a vector of 1s and 0s or something...

The XCVR 2450 covers frequencies around 2.4 GHz and 2.5 GHz and also 4.9 to
5.9 GHz.
When running uhd_usrp_probe it said 2400 to 2700MHz!
(E.g. I assume hardware performance drops off above 2.4 GHz but any reason
why it didn't cap my frequency at 2400MHz?)

I've been through many GRC companion tutorials, which show how to get
various sources up and running, but what if I want to have an input source
that has a straight line or parabola where the value varies based on a time
from a 0 to 5 count?
Using existing blocks can I easily implement a formula
I'm using GRC v 3.6.0 and looking at what can be done with the standard
library.
Although I've been able to apply FM to a wave, I'm still having issues
understanding how to manipulate the variables.
There is a Frequency Modulation block.. but i'm a bit confused about what

I have a 5 questions that are probably relatively straightforward so I
thought it'd be easier to lump them all in together.
Some of these have been touched on in some other disussion threads I found
but I wanted to clarify the answers..
To put things in context, I am doing radar research and am

I was starting to suspect that was the case, thanks for clearing that up

Hi,
I'm quite new to Linux / GNU Radio / these lists and am looking to generate
Signal Pulses.
It seems that gnuradio-radar-mono.py would be ideal for this but wasn't
installed with my GRC 3.6
nor has it been updated for a long time. According to the documentation it
