Can 4Rx simultaneously function in X310

Hi, in the exhibition of MILCOM 2016, I stopped by the booth of NI. They demo a DOA estimation with 4 antenna using X310. But checking the data sheet of X310, I found that X310 only has two RF chains, so how the DOA demo use 4 antenna based on one X310? Thanks,

The X310 is a motherboard, which has two slots for daughterboards. The demo uses two TwinRX daughterboards, which each have two RX channels.

Gotcha. Thank you for your information. BTW, what are the development tools for the X310 and Two TwinRx? Labview only or also good for GNURadio?

No problem! There are several development toolflows for the X310 plus TwinRX. You can use GNURadio and The Mathworks MATLAB & Simulink to program the device now.  NI-branded HW (the USRP 2945 and 2955) will arive in mid-January and support LabVIEW and LabVIEW FPGA. The NI-branded HW will also have CE/UL certification and NI support.

Hello, USRP X310 changes 2 RX channels into 4 input RX channels. What changes need to be made to the underlying VERILOG program?

Hi naniandechunyang,

Could you be a little more specific regarding what Verilog program you are referring to?
