Solution
If you are receiving this error with an NI 2922 or NI 2932, please contact NI support.
If you are receiving this error with a different USRP configuration, there are a few possible causes.
- If you purchased your USRP from Ettus Research, it is possible you have motherboard and daughterboard combinations that are not supported by the NI USRP LabVIEW driver. Specifically, all USRPs with two daughterboard slots must have two identical daughterboards.
- This error can also occur when attempting to use the Write TX command with a USRP that can't generate signals, such as the NI 2945/55 models. Test one of the NI USRP driver examples that receives data, which you can find at C:\Users\Public\Documents\National Instruments\NI-USRP\examples by default.
