Issue Details

Why is my USRP-294x/295x Channel 1 Rx level not accurate after updating the correction data in LabVIEW Communications 1.0 with the Update Device Correction Data.gvi? The following warning message below indicated me to do so. I have already followed the instructions from Why Am I Getting Coerced Reference Levels for My USRP RIO?

Solution

To fix this error, run the attached GVI file in LabVIEW Communications instead of the Update Device Correction Data.gvi that came with LabVIEW Communications 1.0. 


The directions on the front panel are as follows:
  1. Enter the USRP RIO Device Name.
  2. Run the GVI.
  3. Optionally save the current correction data for each channel.
  4. Enter the USRIP RIO Device name, RIO0 for example.
