The created characterization data set is automatically transferred to the active cal unit; the *.calkit file
name appears in the list of available Characterization Data.

System Error Correction State Labels
The following labels in the trace list inform you about the status or type of the current system error
correction.
Label
Meaning
Cal
The system error correction is applied without interpolation. This means that a set of measured correction data is available
at each sweep point.
Cal int
The system error correction is applied, however, the correction data for at least one sweep point is interpolated from the
measured values. This means that the channel settings have been changed so that a current sweep point is different from
the calibrated sweep points. It is not possible to disable interpolation.
Cav
The system error correction uses variable calibration methods to calculate a measurement parameter. This happens for
example, if a Z-parameter is calculated from S-parameters which are partly factory calibrated and partly normalized. This
can also happen, if an S-parameter is measured with different port impedances, or if the analyzer uses a one port
calibration at port 1 and a normalization at port 2.
Ca?
The system error correction is applied, however, the accuracy is questionable because one of the following applies:
 The attenuator settings during the calibration differ from the attenuator settings during the measurement.
 The bandwidth settings during the calibration differ from the bandwidth settings during the measurement.
 The point delay settings during the calibration differ from the point delay settings during the measurement.
 The IF offsets during the calibration differ from the IF offsets during the measurement (see Simultaneous
Measurement with Frequency Offset).
 The detector settings during the calibration differ from the detector settings during the measurement (e.g.
Calibration was performed using the Normal detector while the measurement uses the AVG detector).
 The dynamic bandwidth reduction setting during the calibration differs from the dynamic bandwidth reduction
setting during the measurement.

Off !
The system error correction is no longer applied (e.g. turned off by the user). See also Calibration Overview.

Power Calibration State Labels
The status of a power calibration is indicated in the trace list and in the Calibration Source panel of the
Receiver Power Cal dialog. The following messages can be displayed:
