Hi everyone,
I would like to have some enquiry on the USRP B210 board. As I have tried producing out a simple SINE wave using both the C++ source code and GNU Radio, but both gave me the same results. For example, I've tried sending out a SINE wave centered at 50 MHz, I can see the a spectrum at that frequency on the spectrum analyzer. However, I can also see a spectrum at 100 MHz, 150 MHz, 200 MHz, it just keeps repeating every center frequency. Same goes for the SQUARE wave, just that it repeats on the odd harmonics. I have tried using the GNU .grc examples as well, but it also keeps repeating at all the odd harmonics and doesn't display out the right spectrum.
Please help me on this, as I have been figuring out for about 2 months now.
Thank you.
