Re: [USRP-users] Transmit simultaneously with 2 USRP N210

Hi Basil, You can transmit using multiple USRP radios as shown in this example: https://www.mathworks.com/help/supportpkg/usrpradio/examples/multi-user-transmit-beamforming-with-usrp-r-hardware.html This example uses 2 X310 radios to get 4 transmit channels but you can connect multiple N2xx rad

Hi Don, The only supported way to stop transmissions from SDRu Transmitter block is to insert "zeros" to the signal stream when you do not want to transmit. You need to keep feeding the transmitter with data (zeros or real data). The burst mode is designed to enable the use of these blocks when

Hi Don, First of all, I would use Time Scope without Unbuffer instead of Simulink Scope. It will be much faster. Can you send a picture of the model(s) you use for this test? Do you monitor the underrun and overrun ports to make sure that the model runs in real-time? What is the sample rate (ma
