Correction (Bluetooth)

The Correction trace is the correction curve that the VSA applies to the acquired data to compensate for the frequency response of the input hardware and the input digital filtering, correcting magnitude and phase anomalies in the analyzer's hardware and software signal processing.

The trace is displayed against frequency and is unitless, because it shows a relative correction rather than a measured level. Its trace title is Correction Spectrum.

The correction is derived from calibration data, not from the measured signal, so it is not measurement data and does not indicate anything about the quality of the Bluetooth burst being analyzed. Use it to confirm which corrections are in effect.

For a more detailed description of this trace, including what determines the number of trace points, see Correction (Trace Data).
