4.9.2 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 R&S FSP is fed from the output of the DUT.
Fig. 4.28 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).
4.9.2.1 Calibration of Transmission Measurement
SOURCE CAL
The SOURCE CAL softkey opens a submenu comprising the calibration functions
for the transmission and reflection measurement.
For information on the calibration of the reflection measurement
(
CAL REFL SHORT and CAL REFL OPEN ) and its mechanisms, refer to section
“Calibration of Reflection Measurement” on page 4.234 .
To carry out a calibration for transmission measurements the whole test setup is
through-connected (THRU).
