Re: [USRP-users] Receiving on multiple subdevs using USRP B210

Hi Julian, I made two mistakes in my flow graph that’s why I was not able to receive the messages: 1. I set the BW to 10MHz, should have been 20MHz. 2. I did not connect the output of the decoder to my detector. Really silly mistake. I just realised it now. Thanks a lot for your help. Sincere

Saptarshi, Ok, I see, you did not set set analog filter bandwidth of your USRP to 5 MHz but your signal has 5 MHz bandwidth. This, in combination with the 20 MHz MCR should then be absolutely fine. I'm still not sure how you are trying to detect your signal. Maybe you could share the relevan

Hi Julian, Thanks for your reply. I am basically trying to receive signals of BW 5MHz at two different centre frequencies (2.475GHz and 2.48GHz) using the two subdevs of the B210. The master clock rate gets set to 20MHz which makes me assume that the analog bandwidth for the USRP source is 20 M

Saptarshi, I'm not entirely sure I fully understand what you are doing. You probably need to provide some more details. However, in general, depending on what you master-clock-rate is, doing a 5MHz shift in the DSP does not make much sense if your sample-rate and your analog bandwidth are only

Hi, I am trying to receive on two different centre frequencies (2.475e9 and 2.48e9) using the two receiver chains on B210. Since they are close by, I thought can receive them by setting the “dsp_freq” parameter. Case 1: Subdev: A:A or A:B Nchannel : 1 Centre Frequency: 2.475e9 Sampling Rate:
