Solution
Calibration could fail for the following reasons:
- The actual reference signal applied for calibration was different from the value you specified. Ensure that the reference signal applied is the same as the values that were input.
- The reference signal was not stable over the period of time that the hardware was being calibrated. Ensure that the reference signal specified is free of noise and does not drift throughout the calibration.
- You may be using, in this particular case, a TB-4300B. As per the PXIe-4300 Calibration Procedure, The TB-4300B cannot be used for verification or adjustment of the NI PXIe-4300. You must use a TB-4300, as specified in the "Test Equipment" section.
- You're not following the TB-4300 to Calibrator Wiring Diagram.
- The device is not functioning properly.
