Hello Team,

                 We are transmitting LTE 5MHz samples using xilinx zc706 + AD9371. But getting output of 1MHz at Tx1 port of ad9371.

PFA of Filter wizard profile, 5MHzIQsample.txt, Spectrum analyser screenshot.

Following are settings:

LTE signal of 5MHz sampled at 7.68 MSPS

DUC: 5MHz(Baseband: 7.68 MSPS) upsampled to 122.88MSPS

 

 

Settings at AD9371:

Filter Wizard profile : Tx iqrate 122.88MHz

                                    Tx BW 5MHz

                                    Device clock 122.88MHz

 

Kindly Let us know any additional setting to be done to get 5MHz at AD9371 Tx1 port...

 

Thanks,

Abhishek Naik
