    i am using fmcomms 4 board along with zc706 . i am driving it with no os driver provided on site . i have a doubt , what format is the data being sent through dac and recieved on adc . if we change the format does it affect the data being sent on dac(ad9361) . also how do i switch off the agc control so that i can set the rx_gain from api console.the problem is that my signal amplitude is changing everytime i send data through dac for the same digital signal , it is showing different amplitude . for eg when i send zeroes it shows high amplitude which should be low . pls help.thank you. the data that i wish to send is i q data
