Frequently Asked Questions

When running Bluetooth LE tests, I get a “BT TX LE retrieve analysis results not valid” error message from IQfact+. What does this mean, and how can I fix it?

The capture signal was not able to be analyzed for the measurement that was requested. A couple of likely causes:

  • Signal level too high: It’s possible the VSA was saturated. Increase the RLEV.
  • Capture too short: The analysis needs sufficient data to perform a measurement. Try increasing capture length.
  • Incorrect signal for the analysis: Make sure the signal you are measuring is a valid signal for the analysis type. For instance, you can’t run Bluetooth Low Energy analyses on a Bluetooth Classic signal.
