4.2.5 Effect of the RF source
Information related to the reflection coefficient Γ of the signal source is provided in the
"Γ Correction" dialog box (gamma correction). Γ Correction is used to increase measure-
ment accuracy by correcting the effect of source mismatch on the measured value.

Sensor Γ correction dialog box
►
Open the Γ correction dialog box in the "Sensor "menu
If "Γµ correction" is activated, the measurement accuracy can be increased by specifying
magnitude and phase of source Γ.
