Dear Sung Bok,Lee:
You are using BasicRX/BasicTX daughterboards. These daughterboards do not
have any mixers, so they cannot 'tune' to any frequencies and you have to
supply your own RF frontends to get reasonable performances. All these
daughterboards do for you is just buffering the ADC/DAC and
Dear Sung Bok,Lee:
Forgot to mention - so, in short, all it can do is 'digitally' shifting
signals if you use BasicRX/BasicTX daughterboards. The analog frontends do
not filter any signals (although the daughterboards themselves act as poor
low pass filters with bandwidth of 250MHz), nor mix them
Hi,
A short question for which there is a larger underlying issue: if I connect a
RX RFNoC Radio block to a TX RFNoC radio block, regardless of the presence of
FIFOs in the middle nothing gets transmitted.
The only way it works seems to be by passing through the host by inserting two
fifos and s

Ian and Sugandha,
thank you very much for your comments and also for the attached file.
Sadly, another three questions remain for the moment:
1. In the attached file, there is a series of 48? bits named "Ettus
Padding". Is this an Ettus specific bit sequence and where can I find
information o
Hello we are getting the following error when probing the FPGA in X310 after
installing the created bit file.
Error:Runtime error: Cannot get() on an uninitialized (empty) property.
The testbench runs successfully but after creating the bit file and uploading
it into the SDR we get the error
Hi,
I'm trying to transmit and receive simultaneously using B210 in single
channel mode. The sampling rate for both Tx and Rx is 32 Msamples/s.
I have a recent desktop computer with USB 3 running Debian. The UHD
version is 3.9 LTS. The Tx streamer is started first and then the Rx
streamer (bo

I can answer the question related to the padding. I am not sure about the
rest.
Ettus Padding: An ethernet frame has 6 bytes of destination MAC address and
6 bytes of Source MAC address. Since we use 64 bits/8 bytes of data in one
clock cycle, we add a 6 byte padding in front of the ethernet packe
Hi all,
>From the manual http://files.ettus.com/manual/page_ni_rio_kernel.html ,we
know *Currently, the latest supported kernel version is 4.2.x. *
But the kernel version of ubnutu16.04 is newer than 4.2.x.So we have a
plan to update this?
thank you.
best regards

Christian,
If memory serves me correctly the missing pages are due to that portion of the
design using a proprietary NI ASIC that handles the PCIe interface and the
flash storage of the FPGA config data. Since it handles config it would be
reasonable to assume that circuit also supplies initial
