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.

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:
