Transmission Measurement
This measurement will yield the transmission characteristics of a two-port network. The built-in tracking
generator serves as a signal source. It is connected to the input connector of the DUT. The input of the
R&S ESCI is fed from the output of the DUT.

Fig. 4-25 Test setup for transmission measurement
A calibration can be carried out to compensate for the effects of the test setup (eg frequency response
of connecting cables).

The SOURCE CAL softkey opens a submenu comprising
of the calibration functions for the transmission and
reflection measurement.
The calibration of the reflection measurement (CAL
REFL...) and its mechanisms are described in separate
sections.
To carry out a calibration for transmission measurements
the whole test setup is through-connected (THRU).
