In principle, a reflection measurement involves the same steps as a transmission mea-
surement. Note the following differences:
●
The basic test setup for reflection measurements involves a single DUT and ana-
lyzer port. For instance, you can connect the input of your DUT to port 1 of the ana-
lyzer as shown below.
You can also use the basic transmission test setup, e.g. if you want to measure
reflection and transmission parameters in parallel.
●
The analyzer provides special calibration types for reflection measurements. Use
the calibration wizard and select an appropriate type.
The full 2-port calibration TOSM corrects the system errors for all transmission and
reflection S-parameters.
●
Some of the trace formats are particularly suited for reflection measurements. For
instance, you can display the measured reflection coefficient S
11
in a Smith chart to
obtain the complex input impedance at port 1.
