Try the attached flow graph. I tested it with an Ettus B210.

Hi All,I have a very simple requirement: I want to generate some random signal with 10MHz bandwidth, at the center frequency of 1GHz. How can I make this?1) When I use "band *PASS *filter": [noise source]---[band *PASS *filter]---[qt gui frequency sink] The picture looks like a band *REJECT *filter. When I use "band *REJECT *filter": [noise source]---[band *REJECT *filter]---[QT GUI frequency sink] The picture looks like a *PASS *reject filter. I don't know what happened. 2) And I cannot make noise at centre frequency 1GHz.The filter block warns me: firdes checked failed: 0 < fa <= sampling_freq/2.But if I want to make the center freq at 1GHz, isn't it the sampling_freq should be 2GHz?!It seems to me that it is an too high (impossible) sampling_freq. Thanks and look forward to your help! -- Best Regards, Grandha Woodsend Radio Learner Interest Group
