[USRP-users] X300 MIG

2017-12-11 Thread Rigney, Kevin E via USRP-users
Hello, I'm looking to build a custom design using the DRAM on the X300. There are some custom changes Ettus has made to the MIG and I'd like a little clarification. What's the difference between ui_clk and ui_clk_x2? What clock rate is the ui_clk running at? What clock should I use if I want

Hello Benny Alexander: What is meant is that you must multiply your samples by a constant number, 1.0/(2**15-1), to scale it from 0 - 32767 to 0 - 1 (range accepted by the USRP). Regards, Kyeong Su Shin On Mon, Dec 11, 2017 at 8:50 AM, Benny Alexandar via USRP-users <

Add a multiply block after ishort and multiply by 1.0/(2**15-1) or thereabouts. (If you only are using 14 bits of that 16 b, do 14) On Dec 10, 2017 07:00, "Benny Alexandar via USRP-users" < usrp-users@lists.ettus.com> wrote: > Hi, > > I want to stream an IQ file base band signal using usrp. The
