Thank you very much, Marcus!
But your fosphor RFNoC block does show data in dBm. Can you please explain how
is that done?
Is there a reference I can look at regarding the calibration of the USRP and
converting to dBm?
Thanks again for other clarifications.
Best regards,
Siraj

Dear Siraj,
only regarding the dBm issue:
The USRP is not calibrated. There's no dBm standard anywhere in the
system, only digital power (which is really just the magnitude square of
the complex samples), which is /proportional/ to the physical power, but
not the same. The proportionality factor
Hello All,
I have posted several questions previously trying to understand something but
it only got me more confused.
So let me put this straight.
1- I am trying to read the output of the Log Power RFNoC block *in dBm*.
2- I want to write a CE that compares these samples against a threshold ente
Altug,
If you are using Visual Studio, the easiest thing to do is to create a new
C++ Win32 Console project (or whatever project you need). From there you
can add code files, write new ones or do whatever you need to do. At this
point if the code compiles you will get an executable output.
You wi
Hi Marcus,
I tried axi_wrapper in both SIMPLE_MODE and advanced. When not in
SIMPLE_MODE, I setup s_axis_data_tuser like this:
wire [63:0] vita_time;
wire has_time;
wire eob;
wire [1:0] pkt_type;
wire [15:0] length_adj;
assign has_time = m_axis_data_tuser[125];
assign eob = m_axi
What is your RX gain setting?
Does the unwanted carrier remain when you stop transmitting?
What happens if you use offset tuning of about 1/2 your bandwidth?
Also, yes, it's better if your master clock rate is at least double your
sample rate, but of course, that's not always possible.

Sounds like the header might have not been adapted 100% correctly. Check
whether your noc shell has the right fields set.

I am splitting one of my RFNoC blocks into two different ones, and one
of them is giving me issues. The block is essentially a keep m in n
block, so I only spit out data once in a while. This worked fine when
combined with my other block, but now when I run it independently, it is

Hello -
I am using two USRP E310s with on transmitting and one receiving. I had one
USRP transmit a CW tone at 4.2 GHz and had the other USRP receive at 4.205 GHz.
For some reason, I see two peaks, one at the expected frequency (5 MHz offset
from center) and one at center frequency.

Edit:
I copied the target (rx_samples_to_file) c++ code to the directory
uhd_release_003_009_002/examples/init_usrp and modified CMakeLists file for
rx_samples_to_file. What is next?
Sincerely,

Martin,
thank you very much for your help!
I would like to do this! Could you please give me some further
information what exactly I need to do? As I have never done anything
with FPGAs, I don't know where to start. I have to modify the FPGA
image? Will there be only the GPIO definition or
Dear Derek and Jacob,
Thank you for your time and effort, appreciated.
I followed the instructions (https://kb.ettus.com/
Building_and_Installing_the_USRP_Open_Source_Toolchain_(
UHD_and_GNU_Radio)_on_Windows) step by step, mimicked what it is told, and
successfully finished the building process.
Dear Boris,
that's defined by how much of your CPU is used by the TX flowgraph, and
where you get your data from that you transmit. Generally, 2MHz should
definitely work, if you just generate a constant data stream.
Best regards,
Marcus

I would like to use a sample rate of 2MHz, which produces an 'under run' error.
20,000Hz do work.
The question is what is the USRP E310 sample rate limit?
Thanks,
