System Correction Setting

The Analyzer is supplied from the manufacturer calibrated with the calibration coefficients stored in its non-volatile memory. The factory calibration is used by default for initial correction of the measured S-parameters. Such calibration is referred to as system calibration, and the error correction is referred to as system correction.

The system correction ensures initial values of the measured S-parameters before the Analyzer is calibrated by the user. The system calibration is performed at the plane of the port physical connectors and leaves out of account the cables and other fixture used to connect the DUT. The measurement accuracy of the Analyzer without its calibration with the user setup is not rated.

Normally, the disabling of the system correction is not required for a calibration and further measurements.

The system correction can be disabled only in case the user provided a proper calibration for the Analyzer. The measurement accuracy is determined by user calibration and does not depend on the system correction status. The only rule that should be observes is to disable/enable the system correction before the user calibration, so that the calibration and further measurement could be performed under the same conditions.

If the system correction is disabled by the user, this is indicated in the instrument status bar.
