Hello Wahhab, If I recall correctly, you can *not* change the bandwidth of SBX (always 40MHz), and the sampling rate of the USRP2 (always 100MS/s). What you are actually setting by setting --rate 2e6 is the decimation ratio. The signals will be always sampled at 100MS/s, and then decimated by the

Hi John, Thank you for your reply. We would like to create aliasing. This means that we should set ADC to sample at speed less than Nyquist rate. In our setting, we target RF front end to be 50MHz and ADC speed is 2MHz. The question is how to do it? We use some commands (as shown in my previous ema

Hi Wahhab, This is a fairly basic issue – the ‘bandwidth’ (if that is really what you are really meaning) of signals which can be sampled and correctly reconstituted is related to the sample_rate by Nyquist https://en.wikipedia.org/wiki/Nyquist_ra
