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

Figure 8-8: 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 considered:
●
Interaction of the signal source with the S-parameter device
●
Input of the power sensor, depending on the transmission, expressed by the term
s

s
21
The interaction between the complex reflection coefficient Γ
sensor
of the power sensor
and the reflection of port 2 is expressed by s
22
, see Figure 8-9. If the S-parameter cor-
rection is enabled, this interaction is always considered, regardless whether gamma
correction is performed or not.
