Offset correction
The Offset dialog box is for activating and entering correction factors to effect an increase or decrease
in the measurement result which is not level-dependent. This means that the effects of any attenuators,
directional couplers or amplifiers that are connected ahead of the sensor can be allowed for.
Global
is used to set a fixed correction factor. Frequency-dependent corrections can be made with
Table
.
Both types of correction can be made simultaneously.
S Parameter Device
is for correcting the effects of a twoport connected ahead of the sensor in terms of its
S-parameters. The S-parameters of the twoport must be stored in the sensor (see
Program module
Update S_Parameters
in the sensor operating manual).

The left-hand Table softkey opens a drop-down list with correction
tables. There are 10 tables, each of which can contain up to 80 fre-
quency/offset pairs. The default names of the Tables are Table 1 to
Table 10; however, the names can be changed using the table editor.
