Figure 9-8: 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 taken into
account:
●
Interaction of the signal source with the S-parameter device
●
Input of the power sensor, depending on the transmission, expressed by the term
s
12
s
21
If the S-parameter correction is enabled, the interaction between the complex reflection
coefficient Γ
sensor
of the power sensor and the reflection of port 2, expressed by s
22
, is
always taken into account, regardless whether gamma correction is performed or not.
