FAQ

This is a list of frequently asked questions on the USRP B200/B210/B200mini. If you have questions that are not answered in this document, please contact us - info@ettus.com.

Will the USRP B200/B210 work with USB 2.0?

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?

USB 3.0 is a new standard, and there seems to be wide variation in throughput across various USB 3.0 controllers. Ettus Research maintains a list of benchmarks for various operating systems and USB 3.0 controllers.


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
1 RX 1.92 2.112 2.184 2.508
2 RX 2.148 2.436 2.508 2.64
1 TX 2.184 2.34 2.352 2.22
2 TX 2.76 2.88 2.904 2.64
Full Duplex (1x1) 2.508 2.736 2.796 3.168
2x2 MIMO 3.252 3.588 3.672 4.11 4.092


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:

http://files.ettus.com/manual/page_build_guide.html


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.
