Custom FPGA development

Post by Konstantin » Sun Dec 11, 2016 6:48 am

Hello , Im implementing QPSK transmission system,based on qpsk_tx revision. For this I added PRBS gnerator which feeds symbols for QPSK modulator, the outputs of QPSK modulator I connected with IQ corrector (tx) inputs. I did it like in atsc revison(i mean connections), but I faced again with one problem, how to check spectrum of my implementation. Because I would like to plug in my board and observe spectrum on SA. Now
, when I type bladerf-cli -i and check Signal TAP signals for LMS TX data,there I can observe that some data exist,but I didnt see any spectrum. I checked a lot of tutorial from your web site and still dont understand how to add custom block in FPGA design. Could you pls give me some guidance or clarifications
