3. Run USRP Rx Continuous Async.
If the device is receiving signals you will see data on the front panel graphs.
4. Click STOP to conclude the test.
Verifying the Device Connection Using LabVIEW
Perform a loopback test to confirm that the device transmits and receives signals and is
connected correctly to the host computer.
1. Attach the included 30 dB attenuator to one end of the SMA (m)-to-SMA (m) cable.
2. Connect the 30 dB attenuator to the RX 2 TX 2 connector on the front panel of the USRP
device and connect the other end of the SMA (m)-to-SMA (m) cable to the RX 1 TX 1
port.
3. On the host computer, navigate to <NIDIR>»National Instruments»LabVIEW
<Year>»examples»instr»niUSRP.
4. Open the niUSRP EX Tx Continuous Async example VI and run it.
If the device is transmitting signals, the I/Q graph displays I and Q waveforms.
5. Open the niUSRP EX Rx Continuous Async example VI and run it.
If the device is transmitting signals, the I/Q graph displays I and Q waveforms.
Troubleshooting
If an issue persists after you complete a troubleshooting procedure, contact NI technical
support or visit ni.com/support.
Why Doesn't the USRP Device Appear in MAX?
MAX does not support the USRP device. Use the NI-USRP Configuration Utility instead.
Open the NI-USRP Configuration Utility from the Start menu at Start»All Programs»
National Instruments»NI-USRP»NI-USRP Configuration Utility.
Why Doesn't the USRP Device Appear in the NI-USRP
Configuration Utility?
1. Verify that the latest NI-USRP drivers are installed by running NI Update Service,
available from the Start menu at Start»All Programs»National Instruments»NI
Update Service.
2. Check the LED status to ensure the device is powered correctly. If the LED is blue, the
device is powered correctly using USB. If the LED is orange, the device is powered
correctly using external power.
3. Connect the device to a different USB port of the host computer, if one is available.
4. Ensure that the latest drivers are installed for your USB controller.
