Hi everyone,
I am using NI USRP-2955 with its built in application provided with USRP drivers. The host application named "RX Streaming (4-Channel) host on MXI" is used with FPGA bit file named "niUsrpRio_2945_2955.lvbitx".
Two channels of USRP daughterboard-0 (TwinRX) are tuned at different frequencies. Ch0 of the daughterboard-0 was kept fixed at 870MHz whereas its Ch 1 was varied between 180MHz and 300MHz. No RF input was connected to USRP RF input ports.
I have observed spurious response in ch0 of twinRX at very high power levels (at around -40dBm with 75dB USRP gain. Screenshots of the spectrum observed are attached for reference.
Kindly suggest how to resolve this issue and reason for this spurious response.
Thanks
