Radio Management

Connect and set up SDR hardware

Before you can start interacting with RF signals using Wireless Testbench™ features and a supported NI™ USRP™ radio, you must:

Install the Wireless Testbench Support Package for NI USRP Radios. For details, see Install Support Package for NI USRP Radios.
Connect and set up your radio using the Radio Setup wizard.

Once you have set up your radio, you can use radio objects and object functions to interface with your radio device.
