According to this info provided by Ettus, NI USRP-2900 is equivalent to Ettus USRP B200.
B200, as shown here, is based on Xilinx Spartan 6 XC6SLX75 FPGA and Analog Devices AD9364 RF IC.
Can someone from NI please confirm that USRP-2900 is using the same FPGA and RF IC as B200.
And if that's not the case, please specify the FPGA and RF IC used by USRP-2900.
Thanks for your help.
