The USRP Bus Series provides a fully integrated, single board, Universal Software Radio Peripheral platform with continuous frequency coverage from 70 MHz – 6 GHz. Designed for low-cost experimentation, it combines a fully integrated direct conversion transceiver providing up to 56MHz of real-time bandwidth, an open and reprogrammable Spartan6 FPGA, and fast and convenient bus-powered SuperSpeed USB 3.0 connectivity.
The RF frontend has individually tunable receive and transmit chains. On the B200 and B200 mini, there is one transmit and one receive RF frontend. On the B210, both transmit and receive can be used in a MIMO configuration. For the MIMO case, both receive frontends share the RX LO, and both transmit frontends share the TX LO. Each LO is tunable between 50 MHz and 6 GHz.
All frontends have individual analog gain controls. The receive frontends have 76 dB of available gain; and the transmit frontends have 89.8 dB of available gain. Gain settings are application specific, but it is recommended that users consider using at least half of the available gain to get reasonable dynamic range.
The analog frontend has a seamlessly adjustable bandwidth of 200 kHz to 56 MHz.
Generally, when requesting any possible master clock rate, UHD will automatically configure the analog filters to avoid any aliasing (RX) or out-of-band emissions whilst letting through the cleanest possible signal.
If you, however, happen to have a very strong interferer within half the master clock rate of your RX LO frequency, you might want to reduce this analog bandwidth. You can do so by calling uhd::usrp::multi_usrp::set_rx_bandwidth(bw).
The property to control the analog RX bandwidth is bandwidth/value.
UHD will not allow you to set bandwidths larger than your current master clock rate.
The USRP B200/B210/B200mini/B205mini are derived from the Analog devices AD936x integrated transceiver chip, the overall RF performance of the device is largely governed by the transceiver chip itself.

Certificate of Volatility
Yes, both the USRP B200 and USRP B210 will fall back to the USB 2.0 standard if a USB 3.0 port is not available. There are several things to consider. First, the USB 2.0 data rates are slower. Depending on the USB controller, operating system, and other factors, you may achieve a sample rate up to 8 MS/s with USB 2.0. Also, you may not be able to bus-power the USRP B200/B210 in USB 2.0 mode.
What samples rates should I expect with USB 3.0? USB 2.0?
The performance and throughput of USB 3.0 can vary between host controllers. Ettus Research recommends using the Intel Series 7, 8, and 9 USB controllers. In Linux, the command
lspci will show the USB controller on the system.
When can I power the USRP B200/B210/B200mini off the USB bus?
The experience may vary across various controllers. Generally speaking, bus-power is ideal for SISO operation. If you are using both channels of a USRP B210 we recommend an external power supply. We provide a power supply with the USRP B210.
MIMO operation with the USRP B210 is not recommended when using the USRP B210 on bus-power.
You should not attempt to run the device on bus-power if a GPS-disciplined oscillator is installed.
How much power does the USRP consume?
The table below shows power consumption (Watts) of a USRP B210 run with a 6V power supply. Figures on a 5V supply (USB power), or with a USRP B200 will be moderately lower. The sample rates shown are aggregate sample rates on the USB 3.0 interface.
|5 Msps||15.36 Msps||30.72 Msps||56 Msps||61.44 Msps|
|Full Duplex (1x1)||2.508||2.736||2.796||3.168|
Can I build a multi-unit system with the USRP B200/B210?
It is possible to synchronize multiple USRP B200/B210 devices using the 10 MHz/1 PPS inputs and an external distribution system like to the OctoClock-G. However, USB 3.0/2.0 performance varies dramatically when multiple devices are streaming through the same controller. Generally, we recommend using the USRP N200/N210 if you need to build a high-channel count system.
Can I access the source code for the USRP B200/B210?
Yes. The USRP B200/B210 is supported by the USRP Hardware DriverTM software. You can find the driver and FPGA source code for the USRP B200/B210, and all other USRP models, in the UHD git repository:
What operating systems does the USRP B200/B210 work on?
The USRP B200/B210 is supported on Linux, MAC and Windows.
Does the USRP B200/B210 work with GNU Radio?
Yes. The USRP B200/B210 work with our GNU Radio plugin - gr-uhd.
Does the USRP B200/B210 work with MATLAB and Simulink?
Yes. You need to install the Communications System Toolbox Support Package for USRP Radio.
Does the USRP B200/B210 work with OpenBTS?
Yes. This is a third-party application and you can find instructions here: OpenBTS - Build, Install, Run.
For support, please sign up and contact the OpenBTS mailing list.
What tools do I need to program the FPGA?
The USRP B200 and USRP B210 include a Spartan 6 XC6SLX75 and XC6S150, respectively. The USRP B200 can be programmed with the free version of Xilinx tools, while the larger FPGA on the USRP B210 requires a licensed seat.
Can I use a GPSDO with the USRP B200/B210?
Ettus Research offers a Board-Mounted GPS-Disciplined OCXO and a Board-Mounted GPS-Disciplined TCXO, which are compatible with the USRP B200/B210. These provide a high-accuracy XO, which can be disciplined to the global GPS standard. Please note: When the GPSDO OCXO model is integrated on the USRP B200/B210, the device should be powered with an external supply instead of USB bus power. The TCXO version can be USB bus powered.
