This repository contains tested streaming applications for NI-USRPs.
The USPR 2945 and 2955 (TwinRX) has four RX channels with 80MHz bandwidth (100MS/s). Stream all the channels with full bandwidth will give an overall data throughput of 1.6GB/s: 4 channels x 2 channels (IQ) x 2 Bytes per samples x 100MS/s = 1.6GB/s. The MXIe connection on the USRP can only handle 800MB/s so it cannot stream the full bandwidth. The two SFP+ ports on the USPR gives the possibility to stream the full bandwidth using two x1 Aurora streams (10.3125Gbps per lane)
The USRP 2954 and 2944 has two RX and two Tx channels with 160MHz bandwidth (200MS/s). Streaming all the channels with full bandwidth will give an overall data throughput of 1.6 GB/s: 2 channels x 2 channels (IQ) x 2 Bytes per samples x 200 MS/s = 1.6 GB/s. The MXIe connection on the USRP can only handle 800 MB/s so it cannot stream the full bandwidth. The two SFP+ ports on the USRP give the possibility to stream the full bandwidth using one x1 Aurora streams (10.3125 Gbps per lane) for each channel.
Created an example streaming the full bandwidth of a 2945/2955 to a 6592R using the two SFP+ ports on the USRP connected to two ports on a 6592R. The example can send simulated data or the real data coming from the RX channels
Created an example for record and playback with full bandwidth with a USRP-2954/USRP-2944 to a PXIe-6592R using the two SFP+ ports on the USRP connected to two ports on a 6592R.
Example demostrating how to stream dummy data from the USRP RIO FPGA to the host through PXI. The example was developed using the receiver of a USRP-2945R. Host and FPGA were carefully simplified to the minimum dependencies so it can be compile with other targets.
Each example requires different SW and HW setup. For more info read the readme files in the sub folders.
