Hi Dan,
The E310/E312 has the switchable set of receive and transmit filters which
the B2xx does not. This will impact the noise figure due to the additional
losses of the switches and filters. As with most receivers an external LNA
and filter matched to a frequency of interest will reduce the tot
Lets just focus on Tx for this question.
Lets say I have a Tx channel 900 - 950 MHz wide.
I tune to 925 with 50 MSa/sec sampling rate with a +30 MHz offset tuning
command (Puts LO at 955 MHz).
Is the center frequency of the tuner still at 925 or is it moved based on the
offset?
I have tho
I would like to instantiate a Xilinx cpri core and associated logic in place of
one of the ethernet blocks in the FPGA. I have experience doing this with
Xilinx boards but have a few questions with the X310.
1. Has anyone tried this with the X3x0 SDR's?
2. There is a TI PLL chip that will
Hello,
a fresh pybombs (vanilla gnuradio-default on Ubuntu 16.04) install has
rendered my X310(+WBX-120/SBX) setups unusable. UHD insists that I update
the FPGA image (to compat number 34 which is I guess the Vivado
2017.4-generated one). After that, RX functionality gets crippled, I get

I didn't say it was the amplifier shutting down. I supposed it was the
DC offset cancellation!
Your recording is very interesting. I assume the "spike" you see
happens exactly when you turn on the transmi
Hello,
I'm testing an RFNoC block, I want to measure its performance. I've been
timing the execution time (python script) of a flowgraph with a given input
on the computer to a USRP X310 with the block and back to the computer.
This test is very simple, I would like to know if there are any other
What block are you testing? Most of the blocks I've developed are
deterministic in execution time; I can think of only a few applications
which wouldn't be. A little thought and simulation enables good design to
avoid stalls in a deterministic block with multiple data paths. If you
aren't stalling
