• Onboard FPGA processing
• FPGA: Xilinx Spartan XC3S2000
• ADCs: 14-bits 100 MS/s
• DACs: 16-bits 400 MS/s
• Ability to lock to external 5 or 10 MHz clock reference

FAQ

What are the available resources on the FPGA?

The available resources on the FPGA will vary depending on the code written for it. Based on the 27 March 2012 FPGA code build, the following resources are available:

USRP2 (Xilinx Spartan 3 - XC3S2000 FPGA)

• General Logic
• Memory: 3% free
• DSP Resources: The FPGA does not have DSP resources

Where can I find a compatible SD Card for the USRP2?

Not all SD Cards are compatible with the USRP2; therefore we recommend using the Kingston 2GB SD cards with part number KGS SD2GB as we have found they work reliably.

Proper Care and Handling

All Ettus Research products are individually tested before shipment. The USRP2 is guaranteed to be functional at the time it is received by the customer. Improper use or handling of the USRP2 can easily cause the device to become non-functional. Listed below are some examples of actions which can prevent damage to the unit:

• Never allow metal objects to touch the circuit board while powered.
• Always properly terminate the transmit port with an antenna or 50Ω load.
• Always handle the board with proper anti-static methods.
• Never allow the board to directly or indirectly come into contact with any voltage spikes.
• Never allow any water, or condensing moisture, to come into contact with the boards.
• Always use caution with FPGA, firmware, or software modifications.

	Never apply more than -15 dBm of power into any RF input.
	Always use at least 30dB attenuation if operating in loopback configuration
