The complex reflection coefficient
Γ
sensor
of the sensor, which is also required for the
correction, is prestored in the calibration data memory for many frequencies.

Figure 9-2: Correction of interactions between the power sensor and the signal source
If the gamma correction is performed in combination with an S-parameter correction
(
[SENSe<Sensor>:]CORRection:SPDevice:STATe ON
), the following is consid-
ered:
●
Interaction of the signal source with the S-parameter device
●
Input of the power sensor, depending on the transmission, expressed by the term

The interaction between the complex reflection coefficient
Γ
sensor
of the power sensor
and the reflection of port 2 is expressed by
s

, see Figure 9-3 . If the S-parameter cor-
rection is enabled, this interaction is always considered, regardless whether gamma
correction is performed or not.
