Now I use AD9361 to do Tx function. Mainly I connect the AD9361 to FPGA, using the SPI to control the ENSM,and use the FPGA to configure the registers. I have successfuly made the Rx function. But Tx function was failed. I made this configurations: single Tx, TDD mode, COMS dual port. Mainly the output LO frequency is not correct. When I configure the LO frequency 200MHz,but the output LO frequency is about 608MHz;when i configure it 1GHz, but the output is about 2.422GHz. The output LO frequency seem only about the register 0x005. What problem I faced? The blew pictures are the two frequency output.
set to 200MHz , but output 608MHz
set to1GHz , but output 2.422GHz
I really need your help!Thanks!
