Dear Jon,
that first link points to your own GMail account. We can't do anything
with that, I'm afraid.
Please find the email you're referring to, cite it directly, or link to
it on http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/
Thank you!

Hi Nirmala,
I'm confused, so what *calibrated measurement device* did you use to get
"-80 dbm to -100 dbm"? As Marcus L has pointed out, the values you get
from the USRP are *not* relative to a physical unit.
Please simply don't think the plots that *any* software gives you have
something to do w

My knowledge is limited, therefore, read this with a grain of salt.
However, I wanted to try to help and if something I say does not make sense
then double-check it or someone else may come along and correct me.
I had this same problem when I started with these types of systems. I had

Hey,
the attached flowgraph simply generates a sine which is transmitted
and received by the same USRP in a loop (30dB attenuation + coax cable
between tx and rx port). I used the following USRPs:
- B210
- X300 (1G Eth)
- X310 (1G Eth)
On the Rx side I just added a time sink to view the complex
Dear Kai,
to answer your explicit question first:

unless you're seeing "U" on the console, no, that's not the case:
there's no lost samples.

Hi Oliver,
yep, GNU Radio is just discrete signals, just like in an FPGA – but with
software buffers between software functions :)
That especially means that this is all complex baseband – so, to
represent 20 MHz (= 0.5 MHz · 40), i.e. -10 to +10 MHz, you just need a
sample rate of 20 MS/s.

Hey Marcus,
thanks for the fast reply!
1) I've no Us or something else - everything is fine.
2) Your suggestion (vector source with one period of my sequence) is
exactly what I'm doing in my project (where I noticed the problem).
The sine source was just to create a simple example graph for the

I got the answer to what I was looking for. The "faintest reasonable signal
level" that a typical SDR can process! (Typically around -120 to -130
dBm).!
In my application, I have a bunch of channels through which I can
