The external generator can be used to calibrate the data source by performing either
transmission or reflection measurements.
Transmission Measurement
This measurement yields the transmission characteristics of a two-port network. The
external generator is used as a signal source. It is connected to the input connector of
the DUT. The input of the R&S
FSMR3 is fed from the output of the DUT. A calibration
can be carried out to compensate for the effects of the test setup (e.g. frequency
response of connecting cables).

Reflection Measurement
Scalar reflection measurements can be carried out using a reflection-coefficient mea-
surement bridge.
