Re: [USRP-users] Control LO frequency by FPGA

Dear Xingjian, that won't be possible as is – the tuning happens in the AD9361, and the FPGA communicates with that over a serial link. There's timing accuracy requirements that we can't meet over that serial link, so that's why Ettus' AD936x-based device can't support timed commands on the analog

[USRP-users] Control LO frequency by FPGA

2018-02-13 Thread Xingjian Chen via USRP-users
Hi, I am interested in controlling LO frequency using E312 in such a way that timed command must be used. However, as far as I know, E312 doesn't support timed command for RF front end. So I am thinking if I could write some simple modules in Verilog HDL setting up LO frequency. I am wondering
