In measurement, user calibration or fixture compensation is applied to each measurement point by using interpolation. Even if the measurement points are changed by altering the sweep setups, you don't need to retake the calibration/compensation data.

User frequency - Obtain calibration/compensation data at the same frequency points as used in actual measurement, which are determined by the sweep setups. Each set of calibration/compensation data is applied to each measurement at the same point. If measurement points are changed by altering the sweep setups, calibration/compensation data become invalid and calibration/compensation data acquisition is again required.
