Hi all, Theoretically, in frequency domain, the spectrum for SQUARE wave should be a SINC and for the spectrum of RAMP wave should be decreasing with every odd harmonics. A question that I want to ask is, will I get to see these frequency spectrum in the Spectrum Analyzer after being transmitted out from the USRP B210? As I have tried to send a Square and a Ramp wave using GNU Radio Companion, I see the waveform I want in GNU Radio plot, but I don't see any nice expected waveforms in the Spectrum Analyzer.
Is it because of the IQ Modulation in the AD9361 of the USRP B210 that causes me not seeing the expected results? Or is it because of some configurations not done properly? Hope to get a reply soon! Thank you in advance!
