Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits for electromagnetic compatibility (EMC) stated in the product specifications. These requirements and limits provide reasonable protection against harmful interference when the product is operated in the intended operational electromagnetic environment.
This product is intended for use in industrial locations. However, harmful interference may occur in some installations, when the product is connected to a peripheral device or test object,
or if the product is used in residential or commercial areas. To minimize interference with radio and television reception and prevent unacceptable performance degradation, install and use this product in strict accordance with the instructions in the product documentation.
Furthermore, any changes or modifications to the product not expressly approved by National Instruments could void your authority to operate it under your local regulatory rules.
Caution To ensure the specified EMC performance, operate this product only with
shielded cables and accessories.
Caution To ensure the specified EMC performance, the length of all I/O cables
except those connected to the Ethernet and GPS antenna ports must be no longer than 3 m (10 ft).
Caution This product is not approved or licensed for transmission over the air
using an antenna. As a result, operating this product with an antenna may violate local laws. Ensure that you are in compliance with all local laws before operating this product with an antenna.
Verifying the System Requirements
To use the NI-USRP instrument driver, your system must meet certain requirements.
Refer to the product readme, which is available on the driver software media or online at
ni.com/manuals, for more information about minimum system requirements,
recommended system, and supported application development environments (ADEs).
Unpacking the Kit
Caution To prevent electrostatic discharge (ESD) from damaging the device,
ground yourself using a grounding strap or by holding a grounded object, such as your computer chassis.
1. Touch the antistatic package to a metal part of the computer chassis.
2. Remove the device from the package and inspect the device for loose components or any
other sign of damage.
Caution Never touch the exposed pins of connectors.
Note Do not install a device if it appears damaged in any way.
3. Unpack any other items and documentation from the kit.
Store the device in the antistatic package when the device is not in use.

Note Refer to the USRP device specifications at ni.com/manuals for complete
specifications.
Caution When this symbol is marked on a product, the product could be
damaged if subjected to Electrostatic Discharge (ESD) on the connector pins of any I/O port. To prevent damage, industry-standard ESD prevention measures must be employed during installation, maintenance, and operation.
Caution Do not operate the NI 290x in a manner not specified in this document.
Product misuse can result in a hazard. You can compromise the safety protection built into the product if the product is damaged in any way. If the product is damaged, return it to NI for repair.
Installing LabVIEW Communications System Design Suite
You must be an Administrator to install NI software on your computer.
1. Insert the USB software media into your computer. The installer should open automatically.
If the installation window does not appear, navigate to the drive, double-click it, and double-click autorun.exe.

2. Follow the instructions in the installation prompts.
Note Windows users may see access and security messages during
installation. Accept the prompts to complete the installation.
3. When the installer completes, select Restart in the dialog box that prompts you to restart, shut down, or restart later.
Installing NI-USRP Software
You must install LabVIEW Communications System Design software before you install NI­USRP.
1. Insert the driver software media into your computer. The installer should open automatically.
If the installation window does not appear, navigate to the drive, double-click it, and double-click autorun.exe.
2. Follow the instructions in the installation prompts.
Note Windows users may see access and security messages during
installation. Accept the prompts to complete the installation.
3. When the installer completes, select Restart in the dialog box that prompts you to restart, shut down, or restart later.
Installing NI 2900/2901 Devices
Install LabVIEW Communications System Design Software and NI-USRP before you install the hardware.
Note The NI 2900/2901 device connects to a host computer using a standard USB
connector and USB cable.
1. Power on the computer.
2. Attach the antenna or cable to the front panel terminals of the NI 2900/2901 device as needed for your application.
3. Use the USB cable to connect the USRP device to the computer.
Note You can connect the USRP device to either a USB 3.0 or a USB 2.0
port. If you use a USB 2.0 port, the maximum achievable sample rate may be reduced to 8 MS/s or less. NI recommends that you connect the device to an external power supply when you use USB 2.0.
4. (Optional) Connect the AC/DC power supply to the PWR connector on the back panel of the USRP device, and plug the power supply into a wall outlet.
Note If you plan to use both channels of the USRP device, NI recommends
that you connect the device to an external power supply. However, if you plan to use only one channel, bus power may be acceptable.
You can connect and synchronize multiple NI 2900/2901 devices using an external Reference Clock distribution system such as the Ettus Research OctoClock. However, USB performance
