Use a BasicRX card with any compatible USRP (e.g., USRP1, N210, ...). You do NOT want a B2xx or any card with a tuner or RFIC if you're experimenting with baseband aliasing. If you sample at 2 MHz with a BasicRX, you'll get all the aliases you want. Tuners can produce aliases, but around the l

If you're trying to recreate Mike Ossmann's Bluetooth aliasing experiment, he explains what he did here: https://github.com/greatscottgadgets/gr-bluetooth/blob/master/doc/README.aliasing On 12/29/2017 08:26 PM, Wahhab Albazrqaoe via USRP-users wrote: Thank you Jeff.. Are these filters in soft

The bladeRF SDR can easily be configured to show aliasing. Here's a 6 MHz wide OFDM signal with the transmit filter set to 28 MHz. You can also see the sin(x)/x response of the DAC. bladeRF aliasing Ron On 12/30/2017 03:14 PM, Jeff Long via USRP-users wrote: If you're trying to recreate Mike

Jeff is right, but since I happen to have tackled this problem several times myself, I'll leave some hopefully helpful advice. My use of unicast protocols has mostly been for spacecraft downlinks - what's your use case? In any event, most uni/mult-cast protocols I have come across have been develop
