Introduction

Application Note Number: AN-5501

Authors: John Smith and Jane Smith

Organization: Ettus Research

Last Modified Date: 2016/04/15

Overview

This Quick Start is meant to show you how to put together your new N200/N210. We will start with installing a WBX daughterboard 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. If you have not installed UHD/Gnuradio on your system, please reference the Basic Installation Instructions page. You may also use the Live SDR Environment to preform the verification steps for your USRP. Detailed information on the Live SDR Environment is available at the Live SDR Environment Getting Started page.

Tools Required

  • Philips Screwdriver
  • Torx Screwdriver
  • 5/16” wrench
  • ESD Mat
  • ESD Wrist strap
  • ESD Gloves

Pre-installed Software

Parts Checklist

  • 1 x USRP N200/N210
  • 1 x Power Supply and US Cord
  • 1 x Gigabit Ethernet Cable
  • 2 x SMA-Bulkhead Cables (SMA to MCX)
  • 1 x WBX Daughterboards
  • 6 x Daughterboard Screws
  • One or more Antennas

Proper Handling

All Ettus Research products are individually tested before shipment. The USRP™ is guaranteed to be functional at the time it is received by the customer. Improper use or handling of the USRP™ can easily cause the device to become non-functional. Ettus Research recommends you perform the installation with no power to the USRP and using ESD equipment. Listed below are some examples of actions which can prevent damage to the unit:

  • Never apply more than 0 dBm of power into any RF input.
  • 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.
  • Always use at least 30dB attenuation if operating in loopback configuration

Installation Process

Step 1

Unscrew the 2 screws on the back of the USRP and remove the top 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 6 of the 8 screw holes on the Daughterboard with the USRP Motherboard standoffs (they only go one way). The WBX will only use 6 of the mounting points.

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 6 of the screws provided in the daughterboard

Step 5

It is recommended to connect the bulkhead cables one at a time to avoid confusion. Note which front panel point (RF1, RF2) you install each connector from the daughterboard to (TX/RX, RX2).

Step 6

Install USRP cover with screws

Step 8

Connect the Gigabit Ethernet cable and power cord provided (do not plug in the power adapter to the wall outlet)

Step 7

Attach any Antennas you may have purchased

Step 9

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.

  • Note: The N200/N210 only supports 1 GigE ethernet speeds

Step 10

Power on the USRP (by plugging in the power adapter into wall outlet)

Step 11

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

2.From the terminal/command window:

   $ uhd_fft
