USRP model will support other USRP models if proper consideration is given to sample rates and other parameters. Several software frameworks support UHD: GNU Radio is a Free/Libre toolkit that can be used to develop software-defined radios. This framework uses a combination of C++ and Python to optimize DSP performance while providing an easy-to-use application programming environment.GNU Radio Companion is a graphical programming environment provided with GNU Radio. National Instruments sells the NI USRP 292x series, which is functionally equivalent to the Ettus Research USRP N210. NI also offers LabVIEW support for this device with the NI-USRP Driver. USRP N210 and USRP2 are supported by MATLAB and Simulink. This package includes plug-ins and several examples for use with both the devices. OpenLTE is an open source implementation of the 3GPP LTE specifications as a SDR. Many users develop with their own, custom frameworks. In this case, the USRP device can be accessed with the UHD API. There are also examples provided with UHD that show how to use the API. Products Networked series The USRP N200 and USRP N210 are high-performance USRP devices that provide higher dynamic range and higher bandwidth than the bus series. Using a Gigabit Ethernet interface, the devices in the Networked Series can transfer up to 50 MS/s of complex, baseband samples to/from the host. This series uses a dual, 14-bit, 100 MS/s ADC and dual 16-bit, 400 MS/s DAC. This series also provides a MIMO expansion port which can be used to synchronize two devices from this series. This is the recommended solution for MIMO systems. The X300 and X310 are third-generation USRPs that feature two full-duplex daughterboard slots and feature full 200 MS/s DACs and ADCs. As network interface, 10GBase over SFP+ allows full 200 MS/s on both channels in full-duplex operation. The N300, N310, N320 and N321 are current dual-channel models offering SFP+ connectivity, up to 200 MS/s and optionally sharing of local oscillators and TPM modules for verifiable software deployments. Bus series All products in Ettus Research Bus Series use a USB 2.0 or USB 3.0 interface to transfer samples to and from the host computer. Embedded series The Embedded Series combines the same functionality of other USRP devices with an OMAP 3 embedded processor. The E310, released in November 2014, utilizes the Zynq SoC platform and the Analog Devices AD9361 RFIC for a very compact, embedded USRP. The devices in this
