- Make sure that the device is connected correctly and that all drivers are installed without errors.
- Change the default device ID to "usrp". You can use any other ID. The main point is that it must be a match in "NI-USRP Configuration Utility" and "GP-Simulator".
Make sure the USRP SDR is connected to the computer via USB 3.0.
Launch "NI-USRP Configuration Utility":
Utility default folder "C:\Program Files (x86)\National Instruments\NI-USRP\utilities\USRP-utils.exe"
