Transmission Measurement
The transmission characteristic of a two-port network is measured . The external generator serves as a
signal source. It is connected to the input connector of the DUT. The input of the analyser is fed from the
output of the DUT.

Fig. 4-34 Test setup for transmission measurement
A calibration can be carried out to compensate for the effects of the test setup (e.g. frequency response
of connecting cables).

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