Hi Community, Question - 1
I was working with the UHD version of spectrum sensing code. I have USRP2 with me. I learnt that USRP2 can achieve 50MHz of RF bandwidth with 8 bit samples and 25MHz of RF bandwidth with 16 bit samples. I wanted to know how does this information translates while passing min_freq ans max_freq parameters to the spectrum sensing code. Does it mean (max_freq - min_freq) = 25MHz. Please correct me if I am wrong :teeth: Question - 2 Why the minimum center frequency is set as follows : self.min_center_freq = self.min_freq + self.freq_step/2 Why it simply doesn't take the minimum frequency as we provided. Setting the max_center_freq I understood somehow. Question - 3 In non UHD version of spectrum sensing code the adc_rate was fixed fro USRP-1 i.e. 64M and that was used to calculate usrp_rate while in UHD version of the same code usrp_rate is calculated by the sampling rate we give. I was wondering how does the code manages to work with devices of different sampling rates i.e. USRP-1 with 64M USRP2 with 100M Context : I am trying to scan WLAN channels 1, 6, 11 continuously. So I have to keep working with a total bandwidth of 76 MHz ----- Sumit Kr.
