Overview
This Quick Start is meant to show you how to put together your new X300/310. We will start at the point when you have yet to unpack the boxes and go all the way to being able to ping the device, performing a quick software probe to verify hardware components and finally running a simple FFT demo. This Quick Start does not cover the installation of software on the host computer.
Tools Required
- Philips Screwdriver
- 5/16” wrench
Pre-installed Software
- UHD Latest (http://code.ettus.com/redmine/ettus/projects/uhd/wiki)
- GNU Radio (http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGR)

Proper Handling
Ettus Research recommends you perform the installation with no power to the USRP and using ESD equipment.
Installation Process
Step 1
Unscrew the 2 screws on the top of the USRP and remove cover. (Lift up about 15 degrees and wiggle back as there is a flange on the front part of the cover)
Step 2
Line up the 8 screw holes on the Daughterboard with the USRP Motherboard standoffs (they only go one way).
Step 3
After you have aligned the Daughterboard correctly you can press the Daughterboard on to the connectors below them (you will feel them snap into place).
Step 4
Put 8 of the screws provided in the daughterboard
Step 5
Repeat steps 2- 4 for the second Daughterboard
Step 6
It is recommended to connect the bulkhead cables one at a time to avoid confusion. The Daughterboards and front panel of the X300/310 are clearly labeled as to which cable goes where.
Step 7
Repeat step 6 for the other bulkhead cables
Step 8
Install USRP cover with screws
Step 9
Connect the SFP 1 GigE adapter into USRP SFP port 0
Step 10
Connect the Gigabit Ethernet cable and power cord provided
Step 11
Attach any Antennas you may have purchased
Step 12
On the computer(host) you plan to use to connect to the USRP set the Ethernet adapter to have an IP address of 192.168.10.1 with a subnet mask of 255.255.255.0. Connect the other end of the Gigabit Ethernet cable to your computer.
Step 13
Power on the USRP (button on the front right of the USRP)
Step 14
Ping the device from host computer:
$ ping 192.168.10.2
Step 15
Assuming you have properly installed the UHD driver (http://code.ettus.com/redmine/ettus/projects/uhd/wiki) you can now run this command in a terminal/command window: $ uhd_usrp_probe. This will tell you about the hardware inside of your USRP. The output will look like the following:
insert uhd_usrp_probe output
UHD FFT
Try the UHD_FFT demo that comes with GNU Radio
1. Connect one antenna to RX2 on the left Daughterboard (Daughterboard A)
2.From the terminal/command window:
$ uhd_fft
