h1. Communication chain on USRPs using QPSK
h2. Setup
To successfully connect two USRPs using the inventory mentioned earlier, it is required to have an Ethernet cable connected from the PC to one of the USRPs (in this case the Tx USRP) and then a MIMO cable that connect the Tx USRP to the Rx USRP. This way, the Rx USRP is also connected to the PC. The RF cable is connected from the USRP, using a 30dB attenuator to the Rx USRP. Below is a diagram of the setup. An update to the version of the FPGA image file might needed for LabVIEW Communications. In the NI USRP Utility an update to the images is done as demanded by the software.
