Configuration 4
Configuration summary
• Medium complexity
• Boosted source
• Forward transmission and reflection
measurements only
• Response calibration only
Setup and features
High-power reflection and transmission measure-
ments in the forward direction can be made on
analyzers that provide access to the A channel and
the R channel. Forward reflection measurements
are possible by adding a reverse coupler between
the coupler used for the R channel and the DUT.
This reverse coupler, which is connected to the A
channel, allows the forward reflection measurement.
Calibration
Again only a response calibration is possible since
a reverse measurement cannot be made. When per-
forming the calibration, connect the output of the
second coupler to the attenuator or output coupler
so that the calibration includes all hardware.
